Causes of Lung Cancer – Information You Need to Know

More men and women die from lung cancer than any other cancers. Who is most susceptible to this disease? Nearly 70 percent of the elderly 65 and older will be diagnosed with this disease. Three percent of lung cancer cases have appeared in people younger than 45 years old.

Until the 1930s, cancer of the lungs was not as prevalent but still quite common. However, once there was an increase of tobacco smoking use, lung cancer cases rose drastically. As information and education circulates about the hidden dangers of smoking, lung cancer related deaths are beginning to see a decline. Despite all the education and the public awareness, it’s still a common human cancer. For women, breast cancer is no longer the number one killer. Lung cancer has exceeded breast cancer related deaths.

Lung Cancer Causes

Smoking – Most lung cancer related deaths (about 90 percent) have been associated with smoking. Each time a person smokes a cigarette, they increase their chances of getting lung cancer. Based upon doctors’ formula regarding the quantity of packs to the amount of years smoked, someone who has a 30 pack to year history has a greater chance to develop lung cancer. For those people who smoke two, three or more packs a day, statistics show that one in seven diagnosed will die from the disease. Cigarette smoking is not the only culprit to lung cancer. Cigar smoking and pipe smoking can also lead to the disease at a lower rate. Those who smoke cigars or pipe smoke are five times more likely to get lung cancer than a person who never smoked.

Brain Cancer – Causes, Symptoms

Everyone fears the word cancer. However most types of cancers can be beaten, if you catch it up soon enough, and even if you don’t there are new treatments coming out by the minute everyday that will help you fight and successfully beat cancer. There are however some types of cancers that are more complex in nature than others, brain cancer is the one we’re speaking of and the one we will be focusing on.

Two types of known brain cancer exist, namely: Primary brain cancer (these generally initiate in the brain), Primary brain cancer almost never moves to any other part of the body, so death is brought on by uncontrollable tumor growth within the brain cavity. Then you get metastatic brain cancer or otherwise known as secondary brain cancer (this type of cancer originates in other parts of the body and get transported or should we say it migrates to the brain thus causing the person to circum to secondary brain cancer.

Causes of Brain Cancer

Brain cancer can occur at any age. Studies have shown that two major age groups are affected. From ages 3 to 12 and 40 to 70 are the age groups when brain cancer is formed. Since researchers have been able to gather this data, it has led to the discovery of some risk factors. Workers in certain industries are at a higher risk for brain cancer than workers in other industries. These include, rubber manufacturing, drug manufacturing, and oil refining. Since brain cancer often occurs with members of the same family, heredity is believed to be another cause of brain cancer.

What You Need to Know About Colon Cancer

 

Colon cancer, also known as Colorectal Cancer or Rectal Cancer is one of the leading causes of cancer deaths in the United States. According to the American Cancer Society colorectal cancer is the third most common cancer found in men and women in the United States. It is estimated that this year there will be approximately 108,070 new cases of Colon cancer and 41,000 new cases of rectal cancer in the United States. These cases will result in approximately 49,960 deaths.

 

Colon Cancer is cancer of the large intestine (colon), which is the lower part of the digestive system; it also includes rectal cancer which is cancer in the last 6 inches of the colon. This is where food is processed to create energy for the body. It is also where the body disposes of solid waste matter. After food is swallowed it is deposited in the stomach where it is broken down. It then travels into the small intestine where it is broken down further and the nutrients are absorbed into the body. The food is then feed into the large intestine (colon) which absorbs more nutrients and water from the food and stores any waste matter. The waste matter then passes through the Rectum, which is the last 6 inches of the colon, before being expelled from the anus. There are several layers of tissues that line the walls of the colon and rectum. It is in these layers of tissues that Colorectal cancer starts. The cancer begins in the inner layer and spreads outwards. The stage of the cancer therefore depends on how deep it extends into these layers. There is no single cause of colon cancer, nearly all colon cancers usually begin as small, benign groups of cells called polyps. These Polyps may be large or small and depending on size produce maybe produce little or no symptoms. These Polyps eventually may develop into cancer.

Oral Cancer – What is Oral Cancer

Cancer is defined as the uncontrollable growth of cells that invade and cause damage to surrounding tissue. Oral cancer appears as a growth or sore that does not go away. Oral cancer — which includes cancers of the lips, tongue, cheek, floor of the mouth, hard and soft palate, sinuses, and pharynx (throat) — can be life-threatening if not diagnosed and treated early.

The term oral cancer includes cancers of the mouth and the pharynx, part of the throat. About two-thirds of oral cancers occur in the mouth and about one-third are found in the pharynx. Oral cancer will be diagnosed in an estimated 28,000 Americans this year and will cause approximately 7,000 deaths. It is the 6th most common cancer in men and the 14th most common cancer in women.

Each year, more than 30,000 new cases of cancer of the oral cavity and pharynx are diagnosed and over 8,000 deaths due to oral cancer occur. The 5-year survival rate for these cancers is only about 50 percent. Mortality from oral cancer is nearly twice as high in some minorities (especially black males) as it is in whites. Methods used to treat oral cancers (surgery, radiation, and chemotherapy) are disfiguring and costly. Preventing high risk behaviors, that include cigarette, cigar or pipe smoking, use of smokeless tobacco, and excessive use of alcohol are critical in preventing oral cancers. Early detection is key to increasing the survival rate for these cancers.

Bone Cancer – Information on Bone Cancer

Bone cancer that originates in the bone — primary bone cancer — is rare. Fewer than 2,500 Americans are diagnosed with this type of cancer each year. The condition affects more children than adults. Bone cancer is a malignant (cancerous) tumor of the bone that destroys normal bone tissue (1). Not all bone tumors are malignant. In fact, benign (noncancerous) bone tumors are more common than malignant ones. Both malignant and benign bone tumors may grow and compress healthy bone tissue, but benign tumors do not spread, do not destroy bone tissue, and are rarely a threat to life.

Most of the time when someone with cancer is told they have bone cancer, the doctor is talking about a cancer that spread there from somewhere else. This is called metastatic cancer and can be seen in people with advanced breast cancer, prostate cancer, lung cancer as well as many others. When these cancers in the bone are examined under a microscope they resemble the tissue they came from. If someone has lung cancer spread to bone, the cells of the cancer look and act like lung cancer cells, not bone cancer cells, even after they have spread from the lungs to the bones. They are treated with the same kind of treatment (chemotherapy drugs, for example) that is used for lung cancer.
