Defination: Cancer is a disease in which cells multiply without control, destroy healthy tissue, and endanger life. There are about a 100 types of cancer that attacks us. Cancer strikes people of any age but the chances are more for the middle aged and the elderly.
How Cancer Develops? Cancer develops as a result of abnormal cell reproduction. The body of an adult is made up of billion cells. Normal cells reproduce at exactly the rate required to replace the dying cells, never at a faster rate. Like normal cells cancer cells also reproduce by dividing.
Kinds of Cancer: The various cancers are classified into By a cancer’s primary body site- the site where the cancer develops By the type of body tissue in which the cancer originates Skin Cancer- Skin Cancer grows very slowly and does not spread to any other parts of the body. So this cancer is easy to treat. However a special type of skin cancer called the malignant melanoma is particularly dangerous. Cancers of the digestive organs In this type of cancer the colon, the rectum, sometimes esophagus, liver, pancreas and stomach are affected. Cancers of the respiratory system This type of cancer involves the larynx and the lungs. Lung cancer is the more common of the two kinds. Breast Cancer Three fourth of the breast cancer occur in women aged 40 and above. Female breast cancer patients whose disease is found and treated have good rate of survival Cancers of the Reproductive system The male organ most often affected is the sex gland called prostate. The common cancer that affects women is the cancer of the childbearing organ the uterus. Most cancers of the Uterus affect the lower necklike part which is the cervix. Cancers of the lymphatic systems Cancer of the bone marrow and other blood forming organs is called leukemia. It involves the multiplication of immature white blood cells at the expense of vital blood elements. Cancer of the Urinary System This cancer occurs less often than the cancers of other major body organs. The bladder is the organ usually affected.
Causes of Cancer: The cancer causing agents are called Carcinogens which attack the normal human cells. Some Carcinogens are introduced into the body through the nose, mouth, or Skin some other opening. Various ChemicalsCertain forms of radiationCigarette smoking is the main cause of lung caner.Some industrial chemicals create a cancer hazard for people who work with them.Some cancer including colon and breast occur among blood relatives.The alteration of genes that control cell development may cause cancer.Cancer DetectionThere are seven warning signals of CancerAn unusual change in the bowel or bladder habitsA wound which does not heal quicklyBleeding or discharge in large quantityUnusual lump in the body Difficulty in swallowing foodObvious change in the wart or moleNagging cough or hoarseness
Treatment of Cancer: There are various treatments for Cancer such as
Surgery,Radiation Therapy, Drug therapy, Radiotherapy, Drug therapy.

Diabetes Mellitus
Definition:Diabetes can be caused by too little insulin (a hormone produced by the pancreas to control blood sugar), resistance to insulin, or both. Diabetes is a chronic condition. DM exhibits wide geographic variation in incidence and prevalence Diabetes mellitus (DM) is a chronic metabolic disorder caused by an absolute or relative deficiency of insulin, an anabolic hormone. Diabetes mellitus is defined as a fasting blood glucose of 126 milligrams per deciliter (mg/dL) or more.
Types: There are two basic forms of diabetes. Type 1 diabetes mellitus--formerly known as insulin-dependent diabetes (IDDM), childhood diabetes or also known as juvenile diabetes, is characterized by loss of the insulin-producing beta cells of the islets of Langerhans of the pancreas leading to a deficiency of insulin. It should be noted that there is no known preventative measure that can be taken against type 1 diabetes.
Type 2 diabetes appears most often in middle-aged.
Causes:Diabetes causes many changes in the body. Neuropathy (damage to the nerves) affects sensation to the feet, so that pain is not felt. Diabetes affects approximately 17 million people (about 8% of the population) in the United States. In addition, an estimated additional 12 million people in the United States have diabetes and don't even know it. Diabetes is the third leading cause of death in the United States after heart disease and cancer. Males are at greater risk in regions of high incidence, particularly older males, whose incidence rates often show seasonal variation. People with diabetes often develop bacterial and fungal infections, typically of the skin. When the levels of sugar in the blood are high, white blood cells cannot effectively fight infections. Diabetes is a major risk factor for stroke and coronary heart disease, which includes heart attack.
Serious medical illness and surgery produce a state of increased insulin resistance. Controlling your blood sugar is essential to feeling healthy and avoiding long-term complications of diabetes. Diet, exercise and weight reduction should be the cornerstone of management.
Treatment: The treatment of markedly symptomatic patients with newly discovered type 2 diabetes and glucose levels >400 mg/dL is controversial. Medications used to treat diabetes include insulin. Medications such as thiazides, used to control high blood pressure, and niacin, used for high cholesterol, also may increase blood sugar. Everyone needs regular aerobic exercise, and people with diabetes are no exception. The good news is that the same exercises that are good for your heart and lungs also help lower your blood sugar levels. Drugs and foods known to affect the CYP3A4 system need to be used cautiously in patients treated with atorvastatin, lovastatin, or simvastatin because these agents are largely metabolized through that system.
Diabetes Mellitus Treatment Tips :
1. Serious medical illness and surgery produce a state of increased insulin resistance.
2. Controlling your blood sugar is essential to feeling healthy and avoiding long-term complications of diabetes.
3. Diet, exercise and weight reduction should be the cornerstone of management.
4. Medications used to treat diabetes include insulin. Medications such as thiazides, used to control high blood pressure, and niacin, used for high cholesterol, also may increase blood sugar.
