Today is World Day against breast cancer. I guess it'll be until the very, the importance of having a mammogram for early detection of this cancer
, but as ye are not enough, I will contribute my grain of sand and, incidentally, I culturizar a bit.
The first two links is the only thing that interests me that you read or you do read your wives, daughters, mothers and other women who are about your life.
What is breast cancer?
Breast cancer, like any type of cancer is abnormal cell proliferation and disorderly
, which involves the formation of a tumor or cancer.
Epidemiology
are diagnosed in Spain each year 15,000 new cases and now it will lead figures indicating that one of every 16-18 English have breast cancer.
In the age group 45-55 years, breast cancer is the leading cause of cancer death in women in our country, ahead of lung cancer.
Early detection, when the tumor has not extended or changed, making the cure rate rises to almost 90%.
With all these data, it is obvious the importance of a yearly mammogram after the 45 years (35, in cases of higher risk) and know-how a good self-exploration. The following link explains how.
diagnostic
Other forms of breast cancer are explained here
breast anatomy
The breasts are two protuberances of varying firmness and consistency,
characteristics of women, although some men, certain pathological situations, can have growth
thereof or gynecomastia (not to be confused with adipomastia)
Histologically consists of skin and subcutaneous tissue, adipose tissue (fat), which constitutes 90% and gives way tissue connective and all machinery used for the production and secretion of milk, mammary glands and ducts
The mammary gland consists of two fundamental Elemeno: glandular acini which are milk-producing cells and ducts, a set of " tubes "ramificadoscuyas lights together in increasingly thick tubules ending in one of The 12 to 18 ducts. These ducts have, before entering the nipple, a dilation known as a reservoir or sinus lactiferous sinus lactiferous, beyond the breast, ducts are directed toward the apex of the nipple, where they open the pores or lactiferous lactiferous. Covering part of this web of pipelines, myoepithelial cells are, the function, said roughly, is to "squeeze" the tubes to release the milk.
vascularization and lymphatic drainage
Here I am going to stick, because it is rolling the yarn. Only
remind the importance of tumor spread via the lymphatic system and performing a lymphatic draining function
the results of sentinel node (read the last two paragraphs)
Classification of breast cancer: The
two types primary breast cancer are:
- Ductal carcinoma begins in the ducts that carry milk from the breast to the nipple. Most breast cancers are this type.
- lobular carcinoma starts in the glandular acini.
They are also benign breast tumors such as fibroadenomas and intraductal papillomas. Are abnormal growths, but they are not cancerous and do not spread to other organs breast
There are also other types of breast cancer , if someone wants to delve into the subject, but are less common.
risk factors
- Age and sex: the risk of developing breast cancer increases as you age. Most cases of advanced breast cancer in women over 50 years. Women are 100 times more likely to develop breast cancer than men.
- Family and personal history of breast cancer:
- Genes: The most common gene defects are found in the genes BRCA1 and BRCA2.
These genes normally produce proteins that protect you from cancer.
- menstrual cycle: women who start their periods
early (before age 12) or went through menopause late (after 55) have a risk more
- Childbirth: Women who have never had children or had them only after age 30 have a higher risk of developing breast cancer. Become pregnant more than once or at an early age reduces your risk of breast cancer.
- Hormone therapy: increased risk
- Obesity: The theory is that obese women produce more estrogen, which can
stimulate the development of this cancer.
- Radiation: If you received radiation therapy as a child or young adult to treat cancer
chest area, there is a significantly higher risk of developing breast cancer
.
- Alcohol: the consumption of more than 1 or 2 glasses of alcohol a day may increase the risk of breast cancer.
Symptoms Early breast cancer usually causes no symptoms, reason why regular breast exams are important. As the cancer grows, symptoms may include:
- Breast lump or lump in the armpit that is hard, has uneven edges, and usually painless.
- Change in size, shape or texture of the breast or nipple.
- Fluid coming from the nipple, which may be bloody or purulent
Men also can develop breast cancer and symptoms include breast lump and pain and breast tenderness.
Symptoms of advanced breast cancer may include:
-
Bone Pain - Pain or discomfort in the breast
-
skin sores - Swelling of one arm (next to breast cancer)
- Weight Loss
Treatment Treatment is determined by the size of the tumor and whether it has been spread to the lymph nodes or other areas of the body. Usually, when the tumor is less than 1 centimeter in diameter, surgery is enough to stop cancer and no chemotherapy is needed. However, there are few cases that do not require additional treatment with hormone therapy, chemotherapy or radiotherapy.
