- What Is Cancer? Cancer is a disease which abnormal cells divide
without control and are able to invade other tissues. Cancer cells
can spread to other parts of the body through the blood and lymph
systems. Cancer forms lumps or masses called tumors.

- Causes & Risks Tobacco; The National Cancer Institute says
smoking causes 30% of all cancer deaths in the U.S. and is
responsible for 87% of cases of lung cancer. It doesnt only affect
the lungs, it also can cause kidney, pancreatic, cervical, and
stomach cancers and acute myeloid leukemia. Physical Activity;
Exercising at least 30 minutes a day, 5 days a week lowers the risk
of cancer. Exercises like yoga, aerobics, walking, and running.
Genetics; If you have a family history of cancer, take extra
precautions is vital. When cancer is genetic, a mutated gene has
been passed down. Also, keep in mind, if cancer is in your family
history, it doesnt mean you will develop it. You just have a
greater chance of developing it.

- Causes & Risks contd Environmental Factors; The environment
you are in can cause cancer. Being exposed to asbestos, which is a
group of minerals found in housing and industrial building
materials can cause a variety of medical problems, such as
mesothelioma. Also, people who are exposed o high amounts of
benzene, which is a chemical found in gasoline, smoking, and
pollution, are at risk for cancer as well. Unsafe Sex; Having
unsafe sex can increase your risk of developing a virus called HPV/
HPV is a group of over 100 viruses, medically known as human
papilloma virus. HPV increases your risk factor for cervical, anal,
vulvar and vaginal cancer. Sun Exposure; Skin cancer is caused by
exposure to the UV rays of the sun. A sunburn, or a tan I actually
the result of cell damage caused by the sun. Skin cancer can be
prevented in most cases. Wearing sunscreen when outdoors and
staying out of the sun between the hours of 10 a.m. and 2 p.p.,
when the suns rays are strongest I your best defense.

- Signs & Symptoms Cancer is a group of diseases that can
cause almost any sign or symptom. The signs and symptoms will
depend on where the cancer is, how big it is, and how much it
affects the organs or tissues. If a cancer has spread, signs or
symptoms may appear in different parts of the body. As cancer
grows, it can begin to push on nearby organs, blood vessels, and
nerves. A cancer may also cause symptoms like fever, extreme
tiredness, or weight loss. This may be because cancer cells use up
much of the bodys energy supply, or they may release substances
that change the way the body makes energy from food. Treatment
works best when cancer is found early. Finding cancer early usually
means it can be treated while it is still small and is less likely
to have spread to other parts of the body. This often means a
better chance for a cure, especially if the cancer can be removed
with surgery.

- Benign & Malignant Tumors Benign Tumors - Growth that is
not cancerous - Localized and does not spread to other parts of the
body or invade and destroy nearby tissue - Not harmful and usually
grow slow - Can usually be removed and in most cases they never
come back Malignant Tumors - Tumors that are cancerous - Cancer
cells invade and damage tissues and organs near the tumor - Cancer
cells break away from a malignant tumor and enter in the lymphatic
system or the bloodstream
