In India, the total cancer cases, which were 979,786 in 2010, are likely to go up to 1,148,757 by 2020. There are more than 100 types of cancer. the growth often invades surrounding tissues and can spread to other parts of the body as well (metastasis). Common causes include changes in the lifestyle, infections and hereditary factors. If detected in the early state, many of them can be cured by surgery, radiotherapy or chemotherapy.

What are the warning signs?

Any unusual bleeding or discharge from any part of the body – If you see blood in the urine it may be the beginning of cancer of the bladder or kidney. So better go for a urine test and X-rays and scans if needed. Blood in the stool can occur with piles, fissure (cracks) or cancer of the large intestine. Many times, colon cancer is misdiagnosed and treated as piles. This leads to a lot of delay in detecting the real cause and by the time the right diagnosis is made, it would be too late. So even if it is piles, it requires a detailed check to rule out other causes before you start any form of treatment. These tests are simple like digital rectal examination, proctoscopy (putting a scope into the rectum and examining) or colonoscopy or X-ray test.
