Unseen Passage: Cancer

Cancer happens when the normal cells making up a part of a person’s body start to grow faster than usual, take an odd shape, and stop that part of the body from doing its work. If the cancer lump is found early enough, it can sometimes be removed by surgical operation or killed by treatment with X-rays or gamma rays. But if this is not done soon, stray cells break off from the cancerous part and float off in the blood to start trouble elsewhere. Cancer can start in almost any part of the body—for eg. the lungs, the kidneys, the stomach, the bones, the blood and even the skin. No one really knows why cancer starts. But ideas are becoming clearer about what makes people likely to get Cancer, and doctors are keen to stop people from smoking cigarettes, chewing tobacco which they think may encourage the disease.

Q. Answer the following questions:

  1. What happens to the normal cells in Cancer?
  2. If Cancer is found early, how can it be treated?
  3. Which parts of the body can be affected by Cancer?
  4. What happens if Cancer is not treated in time?
  5. What are the most likely causes of Cancer?

  2. If diagnosed early, cancer tumor can be removed surgically or treated with X-rays or gamma rays.
  3. Cancer can affect almost any part of the body like lungs, kidneys, stomach, bones and skin.
