CANCER RISK DIETS

Red meat has an alarming risk of getting colorectal cancer and it is common among men. Vegeterian diets are best option for people who wants to reduce the risk of getting cancer. Food rich in trans fat can lead to cancer and pleas avoid high fatty foods. Taking more amount of fiber contented food can keep your digestive tract clean and keeps you healthy. Regular exercise with proper diet can help to prevent cancer. A recent report suggests that, increased intake of red meat is proving cancer in most of the cases.

RADIATION ONCOLOGY- CANCER TREATMENT

Radiation is a form of energy released from a radioactive material.In high doses, radiation kills the cells and keeps them from multiplying. Radiation therapy is a one of the best cancer treatment method available. The goal of this therapy is to kill cancer cells. Unlike cancer cells, the normal cells recover soon after the radiation therapy gets over. The scientists try to protect normal cells by restricting the radiation dosage. When they use the irradiation machines, they protect as much of your body as possible while targeting the malignant cells. The radiation for cancer treatment comes from outside separately from radioactive substances that a doctor keeps in our body. Sometimes radiation is used with other treatments, like surgery or chemotherapy.

CANCER CELL BIOLOGY

Cancer cell biology deals with all types of cancer and its biological nature. There are various concepts and facts discussed in detail in cancer cell biology. It deals with causes and effects of various types of cancer. It has more explanations made in various cancerous cells. The main part of cancer cell biology is the BIOPSY TESTING. It detects whether the tumor is malignant or not.

MUTATION BY IONIZING RADIATIONS

There are risks involved in radiation exposures on human in causing cancer. People having radiation exposure more than 200mR are susceptible to get cancer. Prolonged exposure to sun’s ultraviolet radiation causes melanoma. It also proves several other skin malignancies. Even radiations from mobile phones can cause mutation in several cases. There has always been a limit for a radiation dose. It is better to wear lead based attires in radiation hazardous areas. These are some of the common radiation hazards which lead to cancer. So, it’s always better to restrict yourself from entering radiation hazardous areas.

GENES AND CANCER

Genetic abnormalities that are found in cancer may affect two basic classes of genomes. The Cancer-inducing oncogenes are activated in cancer cells, resulting in the formation of new properties, which further results in hyperactive growth and division, protection against death of the cell, abnormality in normal tissue boundaries, and the capacity to become conventional in different tissue situations. Tumor suppressor genes become inactive in cancer cells, leading to the loss of normal functions in the cells, such as precise DNA replication, control over the cycle of cells, orientation inside all cell tissues, and interfaces with the protective cells of the human immune system. " If you are from a cancer heredity, perform tests periodically to stay away from this disease"

CANCER GENERAL DIAGNOSIS

There are various methods of diagnostic tests available for cancer detection. Majority of the cancers can be treated and some can even be completely cured, depending on the nature of the tumor, location, and its maturity. Soon after diagnosis, treatments are given in the forms of radiotherapy, chemotherapy and surgery. Technologies have reached sky high, so that treatments are becoming more and more specific for different varieties of cancer. There has been considerable progress in the analysis of the abnormalities in certain tumors, and which minimize damage to normal cells. The prognosis of targeted therapy drugs which act exclusively on detectable molecules of the cancer patients is mainly influenced by the nature of tumor, as well the degree of maturity of the tumor. In addition, Biopsy grading and the presence of specific molecular markers can be the best tools in identifying prognosis, as well as in determining individual cancer treatments.

LUNG CANCER Vs SMOKING

DNA mutations that crash cell growth can be used for identifying cancer. The substances that cause MUTATION are called as mutagens. Some type of mutagens can cause cancer, which are termed as carcinogens. There are specific substances that can cause a specific type of cancer. Nicotine products (cigarettes, gutka, and tobacco) cause many forms of cancer and it is the cause for 90% of the lung cancer cases. All types of mutagens are not carcinogens. An example of a non mutagenic carcinogenic compound is “ALCOHOL”. Increased alcohol consumption increases the risk of inducing mutation and enhances the cancer cell growth. There are more than 60 types of carcinogens present in cigarette smoke and all carcinogens present in it have the potential to cause cancer.

HOW SMOKING LEADS TO CANCER

There are lot of myths and mistaken beliefs about cancer. Smoking is one of major causes for cancer deaths in the world. There is lot of risk factors in smoking. Smoking can cause various types of cancers. The most common form of cancer arising as a result of smoking is mouth cancer. “The nicotine can give you a pleasant and refreshing mood but it causes MUTATION in the cells present in the body which paves the way for your death through cancer”. Avoiding smoking can greatly reduce the risk of getting cancer. The nicotine taken any form (cigarettes, tobacco, gutka etc,) can cause cancer.

INHALATION OF CARBON MONOXIDE RESULTS IN LUNG CANCER

There are various causes for cancer. Pollution is one of the leading causes for lung cancer. There are some toxic chemicals arising from auto-mobile and industrial exhausts. The prime cause for lung cancer is inhalation of carbon monoxide. This hazardous gas is eventually arising from all fake petroleum and industrial exhaust. “People working in highly polluted environment should compulsorily wear muffler which filters the air that you breathe”. This method reduces the risk of inhaling carbon monoxide. Carbon monoxide causes mutation in lung cells which leads to lung cancer.

Latest cancer treatment: “STEM CELL TREATMENT”

Technology has improved greatly and some best treatments are available nowadays. Radiation therapy and chemotherapy are the classical treatments. The latest treatment that is proving to be successful in most cases is STEM CELL treatment. This treatment involves no big dealing with surgery. Each organ has a unique stem cell which is transplanted into the affected organ leading the way for the development of new organ. Scientists are working hard to cure cancer completely with the help of stem cell treatment. Stem cells result in the formation of new cells for the development of the organ.

THYROID GLAND

The thyroid gland is made up of two lobes: right lobe and left lobe. They are situated in the side of upper part of the trachea. Right lobe and left lobe are connected by thyroid isthmus. The hormone secreted by Thyroid gland is known as Thyroxine. The major functions of thyroxine:
1. Stimulates oxygen consumption by the body and produces a lot of heat.
2. It is necessary for the normal growth of the body.
3. It is necessary for normal growth and maturation of the nervous system of the child.
4. It plays a major role temperature control in the body.

PANCREAS

The pancreas has two types of secretions.
1. Exocrine function: Pancreatic juice is produced in the pancreal acini and poured into the duodenum through the pancreatic duct.
2. Endocrine function: The islet of langerhans produce two hormones namely insulin and glucagon which are directly poured into the blood.
Pancreatic juice is an important digestive juice. It contains high concentration of Bicarbonates and amylase. It also contains lipase, a fat spitting enzyme which converts fats into acids and glycerol. Trypsin and chymotrypsin are proteolytic enzymes which converts protein and polypeptides of amino acids. Amylase is an enzyme which converts starch into maltose.

ENDOCRINOLOGY

Endocrinology is the study of various products secreted by endocrine glands. The endocrine glands are also termed as ductless glands. These glands are known as endocrine glands because their secretions are poured directly into the blood stream without the help of any ducts. The following are the endocrine glands. Pituitary, thyroid, adrenal, pancreas, parathyroid, ovary (female) and testes (male) are the endocrine glands. Each gland secretes a special type of hormone which performs certain special functions. Some of the hormones like vasopressin and oxytocin (female hormones) are highly specific and it triggers certain functions only a particular age.

GALL BLADDER

It is the small pear shaped sac situated on the under surface of the right lobe of the liver. Its duct is called as cystic duct which unites with hepatic duct starting from the liver to form the bile duct. The bile juice is produced in the liver cells and it is stored in the gall bladder. Gall bladder not only stores the bile but also it helps in concentrating the by absorbing the water. Bile always remains in the gall bladder until it is required for digestion. After consuming a fat meal, the gall bladder continues and discharges the bile via cystic duct into the duodenum.

FUCNTIONS OF LIVER

Liver is responsible for secretion of bile. The bile is produced from the liver cells. It contains cholesterol, mucin, water, bile pigments and bile salts. The bile salts activate pancreatic lipase, and aid in the digestion and absorption of fats from intestine. It helps in storage of Glycogen. The absorbed glucose from small intestine is carried to liver. It is converted into glycogen and stored. Whenever it is required it is converted to glucose and utilized by the tissues of the body. It helps in the formation of urea: Nitrogen content is converted to urea and it is excreted in the form of urine. Other functions include production of plasma proteins, storage of vitamin B12 and Iron

WHITE BLOOD CELLS

WBC’s are colorless and it has nucleus. The total WBC content in adult is around 4000-11000/cmm of blood. If the WBC count is more than 11000/cmm it is termed as leucocytosis. This leucocytosis occurs in pyogenic infections and inflammatory conditions. Decrease in WBC count is termed as leucopenia. This condition occurs during typhoid infection. The function of WBC is mainly defense mechanism. They protect the body from the attack of micro-organisms. The granulocytes and monocytes directly dissolve microbes. Eosinophils are compounds which acts as anti allergic. Basophils liberates heparin, which is a pigment required for preventing coagulation of blood.

RED BLOOD CELLS

RBC is disk shaped and it has no nucleus. The diameter of it varies from 6-9microns and thickness 2microns. The normal RBC count in adult male is 5000000/cmm. In female it is around 4.5 million. In infants, the RBC count is around 6.7 million. RBC is composed of stoma protein, lipids, organic and inorganic substances. RBC increases after exercise and excitement. It increases even in high altitudes and in high temperatures. The RBC count decreases in case of anemia. In foetal life, RBC’s are produced only in spleen and liver. After the birth, RBC’s are produced from bones.

HAEMOGLOBIN

It is a complex protein rich in iron content. The iron part of haemoglobin combines with oxygen to form oxy haemoglobin. Carbamino is formed when the globin part combines with carbon-di-oxide. The normal haemoglobin amount is 15g/100ml of blood. Fully saturated haemoglobin (one gram) carries 1.34ml of oxygen. It regulates transportation of oxygen through out the body. It also regulates acid base balance in the blood. Deficiency of haemoglobin in the blood causes anemia. If the concentration of haemoglobin is less than 8g/100ml, it is termed as anemic. Anemia may be caused even due to lack of vitamin B12.

LYMPH

Lymphatic system is connected with circulatory system. It consists of lymph nodes and lymph vessels. The lymph nodes are present in important parts of the body to filter bacteria. They also produce lymphocytes. These lymph nodes are present in areas like neck, axilla, thorax, abdomen and groin. These fluids flow through lymphatic vessels. Lymph is similar to plasma but it contains a very low quantity of protein. It is basically composed of fats and lymphocytes. These glands filter and destroy microorganisms. It carries emulsified fat from intestine to the circulation. The lymph glands transport lymphocytes from lymph gland to circulation.

HEART

The basic organs of circulatory system consist of the heart, arteries, capillaries and veins. Heart is a major organ which is responsible blood circulation. The heart is divided into right and left halves by means of a septum. Each half consists of two chambers, an upper thin walled atrium and a lower thick walled ventricle. The ventricles are distributors of blood. The ventricles are receivers of blood. Tri-cuspid valve is present between right atrium and right ventricle. The opening between left ventricle and left atrium is guarded by mitral valve. These valves permit blood to flow from atria to ventricles.

WATCHING ANIMALS IN THE DARK

Taking photographs and videos of the animals in the dark is a peculiar art. The presence of any dark light can scare away the animals. There are lots of techniques available for capturing pictures of the animals in the dark. The experts take advantage of the fact that majority of the animals are blind to red light. The technique is that people use a torch with a red mask. Even infrared technology has been widely used in watching animals in the dark. Infrared telescopes accompanied with several lighting devices are being used to watch animals during night.

FEATURES OF NOCTURNAL ANIMALS

Domestic cats can easily adapt themselves to darkness. In the wild life, the mechanisms are highly sophisticated. An owl’s eyes are primarily composed of rods and nerve cells. The response varies with the intensity of the light being sensed. An owl can detect a moving mouse in one millionth of the candle power of light. Rodents usually detect their preys with the help of the sense of smell. Even the sense of heat helps certain animals to be active in the night. The snake can record the heat emitted by objects around it and it follows the sensed heat with a great precision.

ANIMALS AT NIGHT

The animal kingdom can be classified into four categories. They are diurnal, nocturnal, crepuscular and arrhythmic animals. The diurnal predators are always active only during the day. Nocturnal animals work usually in the nights. Almost two-third of the animal kingdom is nocturnal. Foxes, bats, mice are nocturnal most of the time. The crepuscular category is active only during twilight hours. The last category that is the arrhythmic animals are active during both day and night. It is amazing how these nocturnal animals can be active during night. The eyes of these animals contain certain special pigments that help them in night vision.

Acai Berry

Combined with proper diet and exercise, the acai berry detox can be an excellent weight loss aid. Its natural combination of antioxidants, essential fatty acids, amino acids, phytosterols, and amino acids work together to help your body function better, process food easier, and burn fat more efficiently. The acai berry contains a generous amount of fiber which promotes a healthy digestive system and helps cleanse your system of fatty foods. The acai berry has been medically and scientifically proven to contain ingredients that aid in weight loss. Not only does it provide a valuable boost to the metabolism, it also suppresses appetite, helps build muscle, and gives a much-needed shot of energy and stamina for those fat blasting workouts and also Acai Berry Increases stamina and energy.

secret ideas of karate

The story is that, an intelligent Indian prince, long ago, described this art, by closely observing insects, birds and beasts, in their fury to protect themselves from the determined onslaught of their fury to protect themselves from the determined onslaught of their enemies. The learned ideas are kept secret. A master will not easily part with a secret secured, after years of sacrificing hard work and loyalty. The master disciple relation was honored in those days of past and even in these present days in a dojo (teaching place). So never reveal the secrets of any arts unless someone taught to you.

RENAL CANCER

Renal carcinoma is type of cancer occurring in proximal tubules of the kidneys. About 80% of the kidney cancer cases are reported from adult men. The cancers occurring in renal parenchyma has a very low survival rate. Radiation therapy and chemotherapy has a poor response in renal cancer treatment. Nephrectomy is the better curative treatment method available. Fracture of hip bone is a rare symptom which arises due to metastasis from renal area to the hip bone. Smoking and alcohol consumption are some of the risk factors that account for renal cancer. Heavy exposure to asbestos and inhalation of certain aromatic hydrocarbons can also increase the risk of getting renal cancer. Surgical treatment usually involves laparoscopy. Trovax is a vaccine which is recently introduced in the treatment of renal carcinoma. Patients who are not fit for surgery can undergo cryoablation. Cryoablation is a treatment which involves freezing of the renal tumors.

PROSTATE CANCER

Prostate cancer is a disease in which malignancy develops in the prostate gland of the male reproductive system. Mutation and proliferation of cells that are present in the prostate gland causes this cancer. Metastases of this cancer are usually associated with bones and lymphatic system. Emission of blood during urination and erectile dysfunction are some of the major symptoms of this cancer. These symptoms appear only during highly mature stages. Men at the age group of fifty are mostly the victims of this cancer.
Heredity and diet are the basic factors associated with prostrate cancer. PSA (prostate specific antigen) is the best diagnostic method available for the detection of prostate cancer. A sample of the suspected prostate tissue is sent for biopsy testing to check the nature of the tumor. High levels of trans fats in the food increases the risk of becoming a victim of this cancer. Frequent usage of some common drugs like aspirin and ibuprofen has the potential to cause prostate cancer.

CERVICAL CANCER

Cervical cancer is a cancer which arises in the cervical region of women due to the proliferation of malignant cells. Symptoms appear only during mature stages. Vaginal bleeding may be the symptom but it is not specific. In the early stages, direct surgery is better option for cervical cancer victims. The development of this type of cancer can be controlled if detected earlier using Pap smear diagnostic method. HPV (human papilloma virus) affected victims have a very high potential for developing cervical cancer if left uncured. Vaccination can help preventing HPV infection. It is important for women at the 40 age group to undergo periodic screening test regularly to escape from being a victim of cervical cancer. Loop Electrical Excision Procedure, commonly known as LEEP is latest innovative diagnostic method available for the treatment of cervical cancer. Hysterectomy is the best surgical treatment method. This method involves complete removal of uterus.

LEUKEMIA

Leukemia is a medical term referring to blood cancer or the cancer in the bone marrow. The characteristics of leukemia include uncontrollable proliferation of blood cells (usually WBC). Leukemia can be classified to main categories, 1) Acute leukemia 2) Chronic leukemia. The general characteristic feature of acute leukemia is the uncontrollable production of undeveloped blood cells. This prevents the bone marrow to produce fresh blood cells. This type of leukemia is common among children. Immediate treatment is required to treat this type of leukemia to stop progression and spreading of the cancer cells. Chronic leukemia characterizes uncontrollable production relatively developed blood cells. This type of leukemia occurs in older age groups. Leukemia can be diagnosed only with the help of medical tests. The major symptom of this type of cancer is the enlargement of liver and spleen. Bone marrow transplantation and radiation therapy are the best treatments available for curing this type of cancer.

COLON CANCER

Colorectal cancer is commonly referred as colon cancer. This cancer can affect three areas which include appendix, colon and rectum. It’s the second major cause for cancer deaths among the western countries. Surgery followed by chemotherapy is the basic treatment available for curing colon cancer. Detection of the tumors is done using colonal endoscopy and DRE (digital rectal exam). PET (positron emission tomography) and DCBA (double contrast barium enema) are some of the other screening methods. Alcohol consumption and smoking has a very high potential to cause colon cancer. Abnormal change in bowel habits and constipation are some of the common symptoms of colon cancer. Weight loss and liver enlargement are the other unusual symptoms of this cancer. Staging is estimated by measuring the amount of the cancer spread. It’s done only after surgery. This cancer is curable if it is detected in the early stages. In the mature stage (distant metastatis), it is less likely to be cured
