Answer 1

Answer:

Cancer is one of the most important non-infectious or non-communicable diseases.

“Cancer is referred to as an ailment characterised by an unrestrained growth of abnormal cells which if untreated and unchecked eventually kills the patient.”

In India nearly four lakhs of people are affected by cancer every year. Out of them two lakhs of people die. It is mainly due to late detection. Many people are not aware of the early symptoms of this disease.

The growth of multicellular animals occurs due to addition of new cells. The old or existing cells divide by mitosis to form new cells. This division is controlled and regulated by some factors. Sometimes, due to unknown reasons, some cells divide in abnormally faster rate to form a lump.

This lump increases rapidly causing ulcers. It causes serious complications in the body. These abnormal cells first destroy the organ and then the whole body. These cells utilize the total food of the body. So the affected person becomes weak, looses his weight and ultimately dies. The tumors, enclosed in connective tissue are called benign tumor and when the tumors grow, it is called as malignant.
