Cancer Prevention

Written by Science Knowledge on 12:22 AM

Now that you understand how cancer works, it’s time to ask how you can stop it. Unfortunately, there’s no single measure to prevent cancer. In fact, your body is already using all the cancer-prevention programs we know about.

Some cancers are closely associated with particular lifestyle risks. For example, sun exposure is linked to skin cancer and cigarettes are tied to lung cancer. Minimize these risks, and you’re likely to avoid the cancers they cause. But many more cancers aren’t so clear-cut. They arise spontaneously and unexpectedly, after a lifetime of bodily wear and tear.

Your best bet is to detect the problem early. If you can catch a cancer before it metastasizes, your odds of conquering it are dramatically better. Unfortunately, many cancers have subtle symptoms that aren’t initially troubling. Some symptoms—like weight loss, fevers, swollen lymph nodes, or a feeling of constant tiredness—may indicate cancer, but are usually caused by something less serious, like an infection. And a few cancers (for example, pancreatic cancer) are virtually undetectable in their early stages.

To give yourself the best odds, you need to be eternally vigilant for problem signs. Some examples include unexplained lumps, persistent coughing, and blood in your stool. However, it’s best to investigate any unexpected change in the way your body works. It’s also essential to keep surveying the territory with breast self-exams, testicular self exams, a yearly physical, and regular colonoscopies after age 50 (or earlier if your family history warrants it).

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
