Cancer is a disease in which cells in the body grow out of control. Cancer is always named for the part of the body where it starts, even if it spreads to other body parts later. When cancer starts in the cervix, it is called cervical cancer. The cervix is the lower, narrow end of the uterus. Also known as the womb, the uterus is where a baby grows when a woman is pregnant. The cervix connects the upper part of the uterus to the vagina (birth canal).
Cervical cancer is the easiest female cancer to prevent, because there is a vaccine and a screening test available. It also is highly curable when found and treated early.

The degree of Newfoundland and Labrador's spoiled breast cancer testing disgrace became rather clearer last week when the region disclosed for the initial time how many patients expired since getting faulty tests.
On the eve of a community investigation into the flawed tests, the local government exposed that 108 patients whose tests were misinterpret have since expired though it might never be understood how many of them, if any, died consequently of missing out on dealing. Another 275 breast cancer suffers who are yet living were given wrong test results.

Women who are fat or have high blood sugar can be more in danger of getting violent breast cancer, research stated. A fresh study is supposed to be the prime to look at how surplus body fat and blood sugar levels might have an effect on the chance of growing different kinds of tumors.
It establish women had reduced risk of low-risk breast cancer if in case they were fat or suffered high blood sugar (insulin resistance), but were at greater risk of more violent tumors. Experts at Umea University in Sweden carried out the study, which was funded by the World Cancer Research Fund and is available in the journal Breast Cancer Research and Treatment.

Geneticists have recently acknowledged a wonderful gene that causes breast cancer to metastasise, the poisonous process by that the disease moves to other organs. Described by the US scientists as a "master regulator," the SATB1 genetic material alters the performance of at least 1,000 other genes inside the tumor cells, stated the study, and available in the British journal Nature.
Until now, it was actuall6y not possible to forecast whether cancer cells in a tumor were intended to attack neighboring tissue, go through the blood system and shape up secondary tumors somewhere else in the body. But the SATB1 protein is simply such an indicator. A tumor in that it is triggered "is intended to metastasise," said Kohwi-Shigematsu.

More than a million Americans suffer heart attacks every year. What you may not know is that many of those don't have any risk factors for a heart attack. A new study said a simple blood test might one day be able to help before it's too late. Heart attacks can happen without any warning. Your first heart attack might be your last. Knowing before it happens makes one new predictive blood test worth talking about. Jante Yarbrough believes if he stays in shape he will stay healthy. "I play basketball and lift weights." At 20, Yarbrough has no risk factors for heart disease. He doesn't smoke, have high blood pressure or cholesterol, but that doesn't mean he's safe. The first sign of heart disease is usually a heart attack. Unfortunately, one out of every three person who has a heart attack won't survive.
Healthy people can benefit from a blood test which measures an enzyme called myeloperoxidase. "Being able to identify those who are at-risk to have coronary artery diseases and be at-risk to have heart attacks is really the majority of the battle," according to Dr. Stanley Hazen, the developer of the MPO blood test. Secreted by the white blood cells, MPO signals inflammation. It releases bleach like substance which damages the cardiovascular system. More than a decade ago, Hazen connected heart attacks in people with existing heart problems to MPO. New studies suggested MPO might be a predictive marker for heart diseases in healthier people. Physicians like George Gabriel are intrigued by the findings. "If you had top levels of MPO, which was the same risk of having an event as if you had high LDL cholesterol," said Gabriel. The six year study of more than 3,000 people at the age of 40 and older showed MPO levels were much higher in healthy people who later developed heart disease or had a heart attack. But were those levels the cause or effect?
"That's the question," Gabriel said. "That's something which needs to be evaluated further." Hazen said the findings might help determine who benefits from an MPO screening test. Yarbrough said he'd take the test if it becomes available. Hazen is confident of his MPO blood test. He had reportedly filed for patents on MPO as a biomarker for cardiovascular diseases. He believes this test will be primarily for those people who don't know they may be at risk for a heart attack.

The important risk factors for developing breast cancer that you cannot change are: i) Age and gender - As you get old the risk of developing breast cancer also gets increased. The majority of advanced breast cancer cases are found in women over age 50. ii) Family history of breast cancer - You may also have a high risk for breast cancer if you have a close relation has had breast, uterine, ovarian, or colon cancer. About 20 to 30% of women with breast cancer have a family history of the disease. iii) Genes - Some people have genes that make them additional prone to developing breast cancer. These genes are normally produce proteins that protect you from cancer. But if a parent passes you a imperfect gene, you have an increased risk for breast cancer. Women with one of these defects have up to an 80% possibility of getting breast cancer sometime during their life. iv) Menstrual cycle - Women who get their periods early (before the age of 12) or went through menopause late (after the age of 55) have an increased risk for breast cancer.
