Cancer is not a contagious disease that spreads easily from one person to the next. However, there are infections that can contribute to the development of certain types of cancer. For example, the human papillomavirus virus is a common sexually transmitted infection, which has been linked to cancer later in life. 

According to the most recent studies, cell phones don't cause cancer. They emit a low-frequency energy that does not harm genes. 

The likelihood of cancer spreading to other parts of the body following surgery is extremely low. Surgeons use special methods and take numerous steps to prevent cancer cells from spreading during biopsies or surgery to remove tumors. If they need to remove tissue from more than one area of the body, for example, they use different surgical tools for each area.

Some people believe cancer spreads after "air exposure" because they feel worse after surgery than before. However, recovering from any operation takes time. Also, doctors sometimes discover more cancer during surgery than was revealed by scans and other imaging tests. In that case, the cancer was already present—it just wasn’t detected by initial tests.

Most cancer patients do not require hospitalization. While receiving cancer treatment, many people often continue to  work part or full time, care for their families and remain active in their communities.

While a high-sugar diet may contribute to excessive weight gain, and obesity is linked to a higher risk of developing several types of cancer, there are no studies to date that conclusively link the consumption of sugar to cancer growth.

Powerlines do not cause cancer. They release a low-frequency magnetic energy that does not cause genetic harm.

No, new plastics that are labeled as "microwave safe" are intended to be used in microwaves and do not emit any harmful chemicals into your food.

There is currently no reputable evidence that links FDA-approved artificial sweeteners to cancer in humans.
