Breast cancer is another type of cancer that occurs in the breast tissue . When
abnormal cells divide without control , they can be great with extra
tissue to form , or tumor , which can be benign or malignant . Benign tumor cells do not spread to other body tissues , usually can be removed and will not arise again .
Malignant tumor cells ( cancer ) can spread to nearby tissues of the
body and break away from the primary tumor into shape form secondary
tumors elsewhere in the body .
Kinds of Breast Cancer
There are several common types of breast cancer :
• infiltrating / Invasive Ductal Carcinoma ( IDC ) occurs in 65 to 85 percent of breast cancer cases . Beginning in the milk duct cells and can penetrate the walls of the channel to attack the fatty tissue . Can spread to the blood or lymph . With a mammogram ( X-ray photography ) is usually seen as an unusual network , small spots or both . Appears as clots that usually feels harder than the surrounding tissue .
• infiltrating / Invasive Lobular Carcinoma ( ILC ) occurs in 5 to 10 percent of breast cancer cases . Contained in the milk -producing glands , and can spread to fatty tissue and anywhere on the body . With
mammograms , can be seen as IDC , but physical examination is usually
not find a hard lump - network rather samara thickness . May occur more than one place in the chest or in both breasts simultaneously .
• Three subtypes are slow-growing invasive Medullary , Mucinous and Tubular carcinomas . That simultaneously occurred in 12 percent of cases of breast cancer . They may be better known than in other malignant cancers .
• Inflammatory carcinoma is a subtype of IDC . Has the characteristics of the breast becomes red , swollen and feels hot , and the skin may thicken and form small lumps . This occurs because of rapid cancer growth and clog the lymph tissue . In 90 percent of cases , the cancer has spread to the lymph tissue when diagnosed . It is an aggressive cancer and is generally done with chemotherapy treatments . Swelling cancer occurs in one out of four percent of the cases .
• Paget 's disease begins in the milk ducts and can be spread on the nipple and areola , causing hardening . If there are no lumps are felt , and biopsy showed no malignant cancer , it's a good sign . Perawarannya together with other malignant cancers .
• Soft tissue tumors : tumors can occur in the supporting tissues of the breast . This is a type of tumor that is not common .
Symptoms of Breast Cancer
Signs and symptoms of breast cancer include:
Lump in the breast or thickened and feels different from the surrounding tissue
Blood out of the nipples
Changes in the size or shape of the breast
Changes in the skin of the breast , for example dimples
Shape of an inverted nipple
Flaking of the nipple skin
Redness of the breast skin , such as orange peel
Causes & Risk Factors
Causes of Breast Cancer
It is not clear what causes breast cancer . Doctors know that breast cancer occurs when some breast cells begin growing abnormally . These cells divide more rapidly than cells in general . The accumulation of these cells to form tumors that can spread to the breast , lymph tissue , or other body parts .
Breast cancer most often begins in the milk production line . Doctors call this type of cancer is invasive ductal carcinoma cancer . Breast cancer can also start from the lobules ( invasive lobular carcinoma ) or cells in the breast .
Scientists identify things that can increase your risk of having breast cancer . But
it is not clear what why some people do not have risk factors develop
cancer , while others who have risk factors never experienced it . It seems that breast cancer is caused by a combination of genetic and environmental factors you .
Breast cancer due to heredity
Doctors estimate that 5 to 10 percent of breast cancer related to genetic mutations in generations in the family . A number of inherited defective gene can increase the likelihood of breast cancer have been identified . Common are breast cancer gene 1 ( BRCA1 ) and breast cancer gene 2 (
BRCA2 ) , both of which increase the risk of breast cancer and ovarian
cancer .
If you have a strong family record with breast cancer or other cancers
, blood tests may help identify defective BRCA or other genes contained
in the family .
Risk factors for Breast Cancer Exposed
The risk factor is anything that makes you more likely to develop breast cancer . But it does have one or even several risk factors does not mean you
will develop cancer - some women with breast cancer do not have any
known risk factors than other women .
Some things that can increase the risk of breast cancer include:
Women . Women are more likely to develop breast cancer than men .
Increasing age . Your risk of developing breast cancer increases with age . Women over the age of 60 years have a greater risk than women with a younger age .
Personal notes with breast cancer . If you have cancer in one breast , you have an increased risk of developing cancer in the other breast .
Family history of breast cancer . If you have a mother , sister or daughter with breast cancer , you have a greater opportunity diagnosed with breast cancer . But generally those who have breast cancer have no family history of breast cancer .
Offspring genes that increase the risk of cancer . Mutations of certain genes that increase the risk of breast cancer can be decreased from parents to children . Mutations of genes in question are BRCA1 and BRCA2 . The gene may increase the risk of breast cancer and other cancers , but they do not make cancer inevitable .
Exposed to radiation . If you are receiving treatment with radiation to the chest as a
child or young adult , you are more likely to develop breast cancer
later in life .
Obesity . Overweight or obese increases your risk of having breast cancer .
Coming months starting at a younger age . Future months that began before age 12 increases the risk of breast cancer .
Menopause is started at an older age . If you are starting menopause after age 55 , you will have more chances of developing breast cancer .
Have their first child at an older age . Women who have recently had children after age 35 can increase the risk of breast cancer .
Postmenopausal hormone therapy . Those who use hormone therapy treatment that combines estrogen and
progesterone to treat the signs and symptoms of menopause have an
increased risk of breast cancer .
Drinking alcohol . Drinking alcohol can increase the risk of breast cancer .
Breast Cancer Prevention
At this time of breast cancer can not be prevented , but can be diagnosed earlier than ever before . Early diagnosis is possible with routine mammography and early examination of the suspected injury . The earlier cancer is known , the greater the chance for cure .
Here is a possible way to help prevent breast cancer :
Low-fat diet ( less than 20 percent ) , with enough fruit and vegetables , and maintaining a healthy weight .
When cancer is found and treated early , there will be more
treatment options that can be taken and have a better chance to heal .
Among the clinical check - ups , do breast self -exam ( BSE ) monthly . Every
woman's breasts are different, and change with age , menstrual cycle ,
pregnancy , menopause , or use of birth control pills or other hormones .
May be normal if you feel breast lumps, swelling or tenderness at specific times , such as before the pregnancy .
Breastfeeding may be slightly lower the risk , especially if it continues for 18 to 24 months . Vigorous exercise at a young age can give long protection . Even mild physical activity in adulthood can reduce the risk .
