One of the most popular DIY cures involves rubbing Vicks VapoRub on the bottom of your child's feet and chest at night, covering with a warm towel for 30 seconds, and repeating a few times. Though it sounds odd, some parents swear that come morning, the nagging cough is a distant memory.
Yet, there is also one type of skin cancer which is a cancer of blood that really causes itchiness. It is the cutaneous T-cell lymphoma which is a growth of white blood cell in the skin. That explains why does skin cancer itch.
That very much depends on the cancer. Cancer is not a specific illness, but rather a type of illness (one caused by uncontrolled cell growth). Besides benign tumors, other types of cancer may also progress so slowly that they never cause a problem. In fact, we all have cancer cells in our body, always.
