Breast Cancer: Developments and other information
First, breast cancer is the cancer that develops in breast cells. It normally begins in the inner lining of the milk ducts or the lobules. Breast cancer, or rather like most cancers can also spread to other parts of the body including the blood cells. This article looks into the recent developments in breast cancer. However, symptoms, causes, and treatments will be highlighted as well.
Types of breast cancer
Breast cancer is a tumor that develops in the breast tissues or cells. They are normally categorized based on the part of the breast they affected first. For instance, the one that starts in the lobules is known as lobular carcinoma, while the breast cancer that developed from the ducts is called ductal carcinoma.
Whom they can affect
Recent studies have indicated that breast cancer not only affects women, but men as well. However, the disease has been more prevalent in women than men have. In the US, research indicated about 450 men develop breast cancer every year. Nevertheless, breast cancer is the most common invasive cancer in females in most parts of th world. It accounts for more deaths in females than any other cancer.
Symptoms of breast cancer
- Development of a lump on the breast
- Armpit pains or breast pains not connected to menstrual period
- Pitting or redness of the skin around the breast
- Signs of a rash around one of the nipples
- Lump or swelling on the armpits
- An area of thickened tissue in a breast
- Discharges from the nipples sometimes it has blood
- Abnormal appearances of the nipple for instance, sunken or inverted
- Changes in the shape or size of the breast
- Peeling, scaling, or flaking of the nipple or skin around the breast
Causes of breast cancer
While medical experts have no clear answer to what the causes of breast cancer may be, some factors have been connected to development of breast cancer. They include:
- Aging: 80% of older women who have reached menopause show higher chances of contracting the disease
- Genetics: Having a family member who has breast cancer may show vulnerability. However, most breast cancers are not hereditary.
- Height: those women who are taller than the average woman have chances of developing breast cancer.
- Certain jobs: Study conducted by French researchers indicated that women who worked at night prior to a first pregnancy had a higher chance of developing breast cancer in the end.
- Dense breast tissue
- Estrogen exposure
- Alcohol consumption
- Radiation exposure
Recent developments on breast cancer
- Oncoplastic surgery: The technique involves reshaping the breast at the time of the initial surgery. This is a new approach to treatments of breast cancer.
- New chemotherapy drugs: The drug targets cancers caused by BRCA mutations.
- Targeted therapies: These drugs are new and they work based on gene changes in cells that cause cancer.
- Bisphosphonates drugs: Help to reduce risk of fracture in the bones
Recent findings from studies
- Zinc can indicate early signs of breast cancer. Scientists from the University of Oxford, UK did the research
- MRI may help predict breast cancer in some women. This study found out that the MRI could help establish the women who are likely to attract the disease.
- Another study found out the possibility of using genetic information in the blood to pick up sensitive amounts of DNA that are useful in breast cancer treatment.
- Another study done by U.S. researchers indicate the likelihood of increasing the survival rate of women with breast cancer through eating Tuna
