• Viruses and Other Infections.
  

  How does cancer come?

  Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.

  How old do you have to be to get cancer?

  About four out of 10 Americans will have cancer at some point in their lifetime. You can get cancer at any age, including as infants and toddlers. But cancer is mostly a disease of middle age and beyond. The median age at diagnosis is 66, meaning that half of all new cases are found before then and half are diagnosed later.

  

  Who is most at risk for getting cancer?

  You’re more likely to get cancer as you get older. In fact, age is the biggest risk factor for the disease. More than nine out of 10 cancers are diagnosed in people 45 and older. Seniors older than 74 make up almost 28% of all new cancer cases.

  Is it more common for older people to get cancer?

  Cancer is more common in older people. The risk of developing cancer increases with age. Many people are surprised by this. You might have heard about children or young people with cancer. But often these stories are shared because they’re rare, and so are particularly shocking or upsetting.

  Why are so many people getting cancer in the UK?

  This is because our cells can get damaged over time. This damage can build up as we age, and can sometimes lead to cancer. The good news is around 4 in 10 cancer cases in the UK could be prevented.

  What factors cause cancer?

  Cancer is caused by both external factors (tobacco, chemicals, radiation and infectious organisms) and internal factors (inherited mutations, hormones, immune conditions, and mutations that occurs from metabolism).

  What causes cancer to start?

  A cancer begins with an error, or mutation, in a cell’s DNA. DNA mutations can be caused by the normal aging process or through environmental factors, such as cigarette smoke, breathing in asbestos fibers, and to exposure to radon gas.

  What cancer can do?

  Cancer cells may be able to influence the normal cells, molecules, and blood vessels that surround and feed a tumor—an area known as the microenvironment. For instance, cancer cells can induce nearby normal cells to form blood vessels that supply tumors with oxygen and nutrients, which they need to grow.

  What causes cancer in cells?

  Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide.
