Cancer Treatments in India
What is Cancer ?
Cancer also known as a malignant tumor or malignant neoplasm, is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.Not all tumors are cancerous; benign tumors do not spread to other parts of the body
Possible signs and symptoms include: a new lump, abnormal bleeding, a prolonged cough, unexplained weight loss, and a change in bowel movements among others.While these symptoms may indicate cancer, they may also occur due to other issues.There are over 100 different known cancers that affect humans.
Tobacco use is the cause of about 22% of cancer deaths.Another 10% is due to obesity, a poor diet, lack of physical activity, and consumption of alcohol.Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants.In the developing world nearly 20% of cancers are due to infections such as hepatitis B, hepatitis C, and human papillomavirus (HPV)
The great majority of cancers, some 90–95% of cases, are due to environmental factors. The remaining 5–10% are due to inherited genetics.
Signs and symptoms
When cancer begins, it invariably produces no symptoms. Signs and symptoms only appear as the mass continues to grow or ulcerates. The findings that result depend on the type and location of the cancer. Few symptoms are specific, with many of them also frequently occurring in individuals who have other conditions. Cancer is the new "great imitator". Thus, it is not uncommon for people diagnosed with cancer to have been treated for other diseases, which were assumed to be causing their symptoms.
