Colon Cancer

http://cancers-list.blogspot.com/

Cancer is a generic term for a large group of diseases that can affect any part of the body. One defining feature of cancer is the rapid creation of abnormal cells that grow beyond their usual margins, and then these abnormal cells can then invade adjacent parts of the body, therefore spread to other organs.

Sadly, it knows no boundaries. Men, women and children are all at risk. According to the World Cancer Research Fund International, there were just about 12.7 million cancer cases seen in the world in 2008. This number was further divided and showed that about 6.6 million of them were male and 6.0 million female. These startling numbers are estimated to increase up to 21 million by the year 2030.

Breaking down those figures even further, these have been found to be the three most common forms of cancer in both sexes:

Lung - the most common type worldwide contributing nearly 13% of the total number of new cases diagnosed in 2008
Breast (women only) - the second most common type with nearly 1.4 million new cases in 2008
Colorectal - the third most common with over 1.2 million new cases in 2008
Gastrointestinal cancers

In fourth place is stomach cancer, along with others that affect the gastro intestine. It is a disease in which bad cells form in organs involved in digesting food or flushing out waste, counting the stomach, liver, pancreas, intestines, colon, and rectum and is classified according to the organ in which it forms as follows:

Stomach (also called gastric cancer) begins in the cells that line the inner layer of the stomach and then grow outward. It is often diagnosed at an highly developed stage, when it can be treated but not so often cured.

Risk factors for developing gastrointestinal cancer

Although not much is known about the causes of many types of gastrointestinal cancer, it is known that the risk factors vary among different types. These include:

Diet: Eating a high-fat diet is a risk factor for small intestine, pancreatic and colorectal cancer. A diet high in salty and smoked foods increases the risk to it as well as a diet high in red meat, processed meats and meats cooked at high temperatures increases risk of colorectal cancer. A diet that includes too few fruits and vegetables increases risk of both colorectal and stomach cancer.

Age: Many types of gastrointestinal cancers increase in frequency as people age.

Cigarettes: Smoking cigarettes increases risk of stomach and pancreatic cancer.

Excessive alcohol use: Excess alcohol increases the risk of liver and colorectal cancer.

Obesity: Being overweight is a risk factor for biliary cancer, colorectal cancer, liver cancer and pancreatic cancer.

Family history of gastrointestinal cancer: If your parent or sibling has been diagnosed with a gastrointestinal cancer.

Diabetes: Having diabetes increases your risk of pancreatic cancer and liver cancer.

Sedentary lifestyle: Exercising too little increases the risk of pancreatic cancer and colorectal cancer.

Cervical Cancer

Most common in women over the age of 30, cervical cancer affects the uterine cervix, a part of a woman's reproductive system. The cervix is a passageway that connects the lowest portion of a women's uterus (womb) to the vagina. Cancer begins in cells, which are building blocks that make up tissues. Normal cervical cells in the tissues of the cervix grow and divide to form new cells, as and when the body needs them. These cells have a definite life span.

When normal cells grow old or get damaged, they die, and new cells take their place. Sometimes, this process goes wrong and new cells form when the body does not need them, and old or damaged cells do not die, as they should. The buildup of such extra cells often forms a mass of tissue called a tumor.

Scientists are not completely sure why cells become cancerous. However, there are some risk factors, which are known to increase the risk of developing cervical cancer. Human papillomavirus (HPV), a sexually transmitted virus is responsible for about 99% of all cervical cancers. There are over 100 different types of HPV, most of which are considered low-risk and do not cause cervical cancer. High-risk HPV types may cause cervical cell abnormalities or cancer. More than 70 percent of cervical cancer cases can be attributed to two types of the virus, HPV-16 and HPV-18, often referred to as high-risk HPV types.

Other risk factors include, multiple sexual partners, becoming sexually active early, smoking, and people with weakened immune system, such as those suffering with HIV/AIDS or transplant recipients on immuno suppressive medications. Certain genetic factors, giving birth at a very young age, multiple pregnancies, long-term use of the contraceptive pill also raises a woman's risk of developing cervical cancer.

Being a silent killer, symptoms of cervical cancer aren't always obvious and it may not cause any symptoms at all until it has reached an advanced stage, where chances of survival are less and the treatment is expensive. Regular screenings are essential to combat this cancer before its spreads.

In most cases, symptoms develop when the cancer becomes invasive and spreads to nearby tissues. When this happens the most common symptom is abnormal vaginal bleeding or bleeding between periods. Other symptoms include bleeding after having sex, pain during intercourse, unusual vaginal discharge, leg pain and swelling and low back pain.

If diagnosed at an early stage, treatment is possible using surgery that is removal of uterus. Radiotherapy is an alternative to surgery for some. In some cases it is used alongside surgery. More advanced cases of cervical cancer are usually treated using a combination of chemotherapy and radiotherapy.

Types of Cancers - Cancer

Cancer types can be grouped into broader categories. The main categories of cancer include:

Carcinoma - cancer that begins in the skin or in tissues that line or cover internal organs. There are a number of subtypes of carcinoma, including adenocarcinoma, basal cell carcinoma, squamous cell carcinoma, and transitional cell carcinoma.

Sarcoma - cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.

Leukaemia
a - cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.

Lymphoma and myeloma - cancers that begin in the cells of the immune system.
Central nervous system cancers - cancers that begin in the tissues of the brain and spinal cord.
