Hi, need to submit a 1500 words essay on the topic What is Breast Cancer.
Download file to see previous pages..."The incidence of cancers is usually written as a number of cancer cases per 100,000 people in the general population. For example in 2001, 40,786 women were diagnosed with breast cancer in the UK. This works out to be 114 cases for every 100,000 women in the UK. The lifetime risk for breast cancer in women is one in nine."
Approximately a quarter of breast cancers affect women under the age of 50, a half occur between the ages of 50 and 69 and the remaining quarter develop in women who are 70 years or older. Women who start menstruating early in life or who have a late menopause have an increased risk of breast cancer.
Having no children and being older at the time of the first birth both increase the lifetime incidence of breast cancer. The risk of breast cancer in women who have their first child after the age of 30 is about twice that of women having their first child before the age of 20.
Early menstruation or late menopause also increase the risk of breast cancer in women. The age at the time of first pregnancy also greatly affects the chances of being infected with breast cancer. Late first pregnancies increase the chance of breast cancer.
Exposure to radiation, for example too many chest X-rays, also greatly increases the chances of breast cancer. Some studies have shown a relation between consumption of alcohol and the incidents of breast cancer.
, but such relationship is not consistent and may be influenced by dietary factors other than alcohol.
Recent Research on Breast Cancer
"Cancer Research UK is the major supporter of breast cancer research in the UK, with an annual spending of over 20 million. Research has shown that it is mainly the DNA damage which may occur during a woman's lifetime which leads to breast cancer. Very rarely, a faulty and highly risky gene may have been inherited from the mother or father of the victim.
