Breast cancer is the most common type of cancer in women after skin cancer. All around the world millions of people are suffering from this cancer and as per the recent statistics more than 22 percent of all cancers diagnosed in women are breast cancers. The latest cancer information up to the year of 2008 show that in the same year 458,503 deaths occurred due to breast cancer that amounts to 13.7% of cancer deaths in women. Though there is no conclusive and permanent treatment for breast cancer people affected with breast cancer can survive much longer if the disease is diagnosed earlier and put to proper treatment and medications. Especially in the medically developed nations the survival rate of the breast cancer affected people is much higher than in the developing and underdeveloped nations. According to the latest available statics 8 out of 10 women in England who suffer from breast cancer survive at least 5 years with the disease. Before going into more detailed discussion let us look at the clinical definition of breast cancer.
The clinical definition of Breast Cancer
Breast cancer normally happens in the inner lining of the milk ducts in the breast or the lobules that supply the milk and breast cancer is caused mainly by uncontrolled cell growth in the portion of the breast mentioned above. The uncontrolled growth of the breast cells that is responsible for the breast cancer can occur in men also though most cases of breast cancer happen in women. The clinical definition of breast cancer distinguishes between two major types of breast cancer, the type of breast cancer that happens in the milk ducts of the breast and the breast cancer in the lobules that supply milk to the ducts of the breast. The first type of breast cancer is more common than the second one and is called ductal carcinomas. The second type of breast cancer in the lobules of the breast is called lobular carcinomas. There are numerous other types of breast cancer that can affect singularly or in simultaneously in combination and survival as well as cure rate of the breast cancer affected people largely depend upon these types and their status.
Some astonishing facts of breast cancer in USA
Breast cancer is one of the most common types of cancer in women in USA. According to the latest information provided by the American Cancer Society, 200,000 new cases of breast cancer are diagnosed every year making the country to be most vulnerable to the breast cancer in the world. Recent statistics show that there are close to 2.5 million survivors of breast cancer in the country and in 2011 alone 40,000 women will die of breast cancer.
Different Types of Breast Cancer
Breast cancer can be of varying types according to the location of the uncontrolled cell growth in the breast and malignant syndromes. Here we are introducing some of the most common types of breast cancer.
Noninvasive Ductal Carcinoma:
The cancer in the inner lining of the milk ducts is called ductal carcinoma and when this type of cancer does not take a malignant and invasive form it is called to be noninvasive ductal carcinoma or more commonly Ductal Carcinoma in Situ (DCIS). Being noninvasive or non-malignant this cancer has a higher rate of survival and most of the patients if diagnosed earlier are cured from this type of breast cancer.
Invasive Ductal Carcinoma:
This type of breast cancer starts in the ducts of the breast and spreads in the surrounding tissues and 80% of the invasive breast cancers are basically this type of cancer.
Invasive Lobular Carcinoma:
The type of breast cancer that starts in the milk supplying glands of the breast and spreads in other tissues of the breast is called Invasive Lobular Carcinoma and this type of cancer accounts for 10% of all the invasive breast cancers in the world.
There are some other types of breast cancers that are not that much common and comparatively only a few cases are diagnosed with these types of breast cancer. Some of the other types of breast cancer which are uncommon in the regular diagnosis of breast cancer include Mucinous Carcinoma, Medullary Carcinoma, Inflammatory Breast Cancer, Triple-Negative Breast cancer, etc.
Our description and introduction to the various clinical aspects and types as well as statistical accounts regarding the breast cancer is limited to the purpose of providing the reader the very basic and relevant information regarding the disease.
