Cancer is not 100% preventable in all cases, but there are specific steps any individual can take to reduce or minimize chances of cancer:
1) Lifestyle adaptations: Certain lifestyle factors increase chances of cancer. Some are universally agreed upon, like reducing physical weight, abstaining from alcohol, not smoking, and protecting yourself from the sun. Others are possible or probable, but sometimes debatable, like certain foods you eat, i.e. red meats or processed foods. However, it is generally agreed that diet and exercise go a long way.
2) Get your check-ups: Routine physicals and age-advised screenings can often detect cancers or warning signs of cancers. Breast exams, colonoscopies, testicular examinations, and looking over your entire skin can find early signs of many common cancers so they can be nipped in the bud before they turn into serious problems.
3) Know your family history: Family history is not always an accurate predictor of cancer, but some kinds strike some families more than others. Incidents of colon cancer, for instance, that take place while someone is middle aged, means that descendants and relatives should probably get checked out earlier than the general population is advised to begin to.
4) Remove risky parts: This is much easier accomplished if examination schedules and guidelines are adhered to. A person with breast cancer might decide to have both breasts surgically removed and then replaced with implants in order to negate future risk. Someone with suspicious moles or atypical nevi on the skin can have them removed by a dermatologist to prevent any risk of melanoma.
