Can Cancer be Prevented?

Most of the cancers can either be prevented or the risk of developing cancers can be reduced to a very great extent.

Prevention of cancer, by avoiding its potential causes, is the simplest method.

First and foremost is to stop smoking tobacco and consuming excess alcohol.

Avoiding excess sunlight (by decreasing exposure or applying sunscreen).

Avoiding exposure many of the chemicals, radiation and toxins.

Avoiding contact with certain viruses and other pathogens is likely to prevent some cancers.

There are two vaccines currently approved by the U.S. Food and Drug Administration (FDA) to prevent specific types of cancer.

Vaccines against the hepatitis Bvirus, which is considered a cause of some liver cancers, and vaccines against human papillomavirus types 16 and 18, which, according to the NCI, are responsible for about 70% of cervical cancer.

People with a genetic predisposition to develop certain cancers and others with a history of cancers in their genetically linked relatives currently cannot change their genetic makeup.

However, screening studies for cancer, while they do not prevent cancers, may detect them at an earlier stage when the cancer is more likely to be potentially cured with treatment. Such screening studies include breast exams, testicular exams, colon-rectal exams (colonoscopy), mammography, PSA levels,prostate exams, and others.

The earlier cancer is disproved or diagnosed and treated, the person will be better served.
