Breast cancer can affect women and men alike and is the second most common type of cancer worldwide next to lung cancer. Breast cancer is the fifth most common cause of cancer death worldwide. Among women, breast cancer is the most common cancer worldwide. Breast cancer is more prominent in industrially developed countries than in countries not industrially developed.
Breast cancer symptoms can be detected when a lump, tumor, or cyst grows large enough to either be felt or seen on a mammogram. Sometimes a tumor isn’t found for many years. Breast cancer symptoms don’t often manifest themselves until the cancer is already in its later stages of growth, and may have already metastasized to other more vital areas of the body. That is why it is so important for women to regularly get checked.
Breast cancer is the second most common type of cancer after lung cancer (10.4% of all cancer incidence, both sexes counted) and the fifth most common cause of cancer death. Worldwide, breast cancer is by far the most common cancer amongst women, with an incidence rate more than twice that of colorectal cancer and cervical cancer and about three times that of lung cancer. However breast cancer mortality worldwide is just 25% greater than that of lung cancer in women. In 2005, breast cancer caused 502,000 deaths worldwide (7% of cancer deaths; almost 1% of all deaths).The number of cases worldwide has significantly increased since the 1970s, a phenomenon partly blamed on modern lifestyles in the Western world.
All the treatment for breast cancer including surgery, chemotherapy, radiation therapy, immunotherapy, and vaccine therapy, has their own side effects. But women with breast cancer experience more side effects from chemotherapy. According to reports, some breast cancer patients treated with chemotherapy experience congestive heart failure after some months. But the rate of cardiac toxicity is lower with some recently found chemotherapy agents. Women undergoing chemotherapy for breast cancer may experience side effects such as infections, low blood counts, dehydration, nausea, fever, etc. Some may even require hospitalization or emergency department care.
There are ways to prevent breast cancer or help to prevent the condition. Having more children, breastfeeding, and exercising three times per week for an hour each time. This exercise regimen has been found to lower the risk of breast cancer by up to 40 percent. High intake of soy, folic acids, and avoiding secondhand smoke also help to prevent the development of breast cancer.
Metaplastic carcinoma: Met plastic carcinoma represents less than 1 percent of all newly diagnosed breast cancers. This lesion tends to remain localized and contains several different types of cells that are not typically seen in other forms of breast cancer. Prognosis and treatment is the same as for invasive ductal carcinoma.
Breast cancer is the most common cause of cancer in women and the second most common cause of cancer death in women in the U.S. While the majority of new breast cancers are diagnosed as a result of an abnormality seen on a mammogram, a lump or change in consistency of the breast tissue can also be a warning sign of the disease. Heightened awareness of breast cancer risk in the past decades has led to an increase in the number of women undergoing mammography for screening, leading to detection of cancers in earlier stages and a resultant improvement in survival rates.
Most lumps turn out to be fibrocystic changes. The term “fibrocystic” refers to fibrosis and cysts. Fibrosis is the formation of fibrous (or scar-like) tissue, and cysts are fluid-filled sacs. Fibrocystic changes can cause breast swelling and pain. This often happens just before a period is about to begin. Your breasts may feel lumpy and, sometimes, you may notice a clear or slightly cloudy nipple discharge.
