Why cancer risk factors always involve being over 55?

When looking at risk factors for cancer, why is being over the age of 55 one of the risk factors?  What makes that age so special?  Couldn't a person in their 20s or 30s get cancer as well? 

By the way, can you get colon cancer at 34?

    As you become older, the risk for cancer increases.

    * Chronic Hepatitis B or C causes hepatocellular carcinoma (Liver cancer).

    * Cigarette smoking will cause lung cancer, cancers of the larynx and mouth, and pancreatic cancers.Tobacco use is the most important risk factor for cancer and is responsible for approximately 22% of cancer deaths.

    * Human papilloma virus causes cancers of the cervix, vulva, vagina, penis, anus, mouth, or throat.

    * Ultra-violet radiation causes skin cancer (melanoma).

    * Epstein-Barr Virus has been implicated in several diseases, including infectious mononucleosis, Burkitt's lymphoma, Hodgkin's lymphoma, stomach cancer, nasopharyngeal carcinoma, multiple sclerosis, and lymphomatoid granulomatosis.

    Cancer treatment can be more challenging and complicated for older adults. This is because older adults are more likely to have chronic health conditions, such as diabetes or heart disease. Even when you are healthy, your body will most likely respond differently to treatment than a younger person’s body. For example, older adults are more likely to have serious side effects from chemotherapy.

    Prostate cancer is around 22 times more frequent among elderly men than among younger men. The corresponding most frequent cancers among elderly women, making up 48% of all malignant cancers, are breast (248 per 100,000), colon (133 per 100,000), lung (118 per 100,000) and stomach cancer (75 per 100,000).

    Cancer is the second leading cause of death globally, and is responsible for an estimated 9.6 million deaths in 2018. Globally, about 1 in 6 deaths is due to cancer.

    Obviously younger people do get cancer, but for certain types of cancer, age is a risk factor indeed. Your cells replicate all the time, but as we get older, the risk of they replicating incorrectly and eventually ending up as a malignant cells, is higher. Therefore why age is a risk.

    And yes, people that are in their 30's do get colon cancer.

    Because of the nature of most cancers. Not all do involve being older either.

    That's what studies are for. All you have to do is start counting the number of people with cancer and noting their age. The incidence of cancer is highest in certain age groups. It varies with specific cancers. Some cancers are more common in children while others are more common in older people.

    Once you record all of those and make those observations related to age then you can then guess (hypothesize) explanations for those observations. In oder to prove the causes or links then that's what more studies are for.

    The incidence of colon cancer is rare for the age of 34. Most cases are over the age of 50 which is why colonoscopies are performed starting at that age.

    Approx 80% of cancers occur in people over the age of 50.

    Most cancers are due to aging or take many years to develop.

    This makes being older a risk factor.

    It does not make it impossible for someone younger to get cancer, just less likely.

    Look, there are many toxins in the world - they increase by time. Even, if you got in contact with a cancer causing material in your 20ies, in can take up to 20 years until the body is too weak to keep these cells under control. There is no special age. You can even get cancer with the age of 1.

    One of the biggest cancer causing material is all radioactive materials, followed by chemicals...and the world is full of it.

    Of course you can get it earlier, or later, or not at all. Risk factor mean chances get worse.
