Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these to spread, either by direct growth into adjacent tissue through invasion, or by implantation into distant sites by metastasis (where cancer cells are transported through the bloodstream or lymphatic system). Cancer may affect people at all ages, but risk tends to increase with age. There are many types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Severity of symptoms depends on the site and character of the malignancy and whether there is metastasis.

Cancer prevention is defined as active measures to decrease the incidence of cancer. Much of the promise for cancer prevention comes from observational epidemiologic studies that show associations between modifiable life style factors or environmental exposures and specific cancers. Use of exogenous hormones, exposure to ionizing radiation and ultraviolet radiation, certain occupational and chemical exposures, and infectious agents. Alcohol consumption, Smoking (although 20% of women with lung cancer have never smoked, versus 10% of men. Cancer however, compared with tobacco exposure, the magnitude of effect is modest or small and the strength of evidence is often weaker. Do not take the Alcohol and No Smoking.

All types of cancer are different, and they affect the body in unique ways. If you have been diagnosed with liver cancer, make sure you remember that when you carry out your research. Cancer information about the lungs might not help you out much. You should always get your cancer information first and foremost from your doctor or GP. If you aren’t comfortable with the amount of information they seem to have for you, you may want to consider finding some other sources. Doctors do their best to stay on top of the latest studies and findings, but it is possible that your doctor may be unaware of up-to-the-minute developments and research, they are very busy people after all.

Remember when looking up cancer information online that you can’t trust everything you read. There is a lot of great information out there, and there is a lot of cancer information that is just plain wrong. Anyone can write up an article and slap it up online, but that doesn’t mean the information included is correct. That is where the web gets tricky and why I recommend you discuss your findings with your doctor before you take it as the truth. There are great sites out there, don’t get me wrong, just be aware of what source you trust when looking for cancer information on the Internet.

According to the NCI report, mortality rates “decreased for 12 of the 15 most common causes of cancer death in men (i.e., cancers of the lung, prostate, colon and rectum, bladder, kidney, stomach, brain, and oral cavity as well as leukemia, non-Hodgkin lymphoma and myeloma).” Among women, mortality rates “decreased for 10 of the 15 most common cancers (i.e., breast, colon and rectum, stomach, kidney, cervix, brain and bladder cancers as well as non-Hodgkin lymphoma, leukemia, and myeloma).” Unfortunately, while deaths from blood and cervical cancers decreased, those from liver cancer and lung cancer increased for women.

If you or a loved one are diagnosed with cancer – whether bone cancer, skin cancer, ovarian cancer, or some other form – it’s natural to jump to conclusions. That is why it is imperative to gather all of the information possible on the form of cancer and its treatments. Thankfully, the Internet can provide a wealth of information on cancer and cancer treatments. Becoming education about the disease your fighting may well be your best weapon in beating the disease. Information gives you the power to ask the right questions of health care providers, better understand your options, and pave the way to making an informed decision about cancer treatment.
