breast cancer
Introduction
Introduction to breast cancer Breast cancer (mammaryofaccessorymamma) refers to cancer that occurs in the accessory breast, which occurs in the temporal region. The rare sites are the subclavian region, the abdomen and the vulva region. Wang Faheng (1993) reported 4 cases of paraneoplastic breast with nipple and areola. , the mammary gland, there are only nipples, and some have lactation. Due to the presence of the glandular gland, during the menstrual period, during the physiological changes such as pregnancy and lactation, there may be pain in the corresponding area and the breast, and even lactation with the lactation of the breast. Therefore, there is a glandular accessory. The breast has the same potential for breast cancer as the breast in the normal part. basic knowledge The proportion of illness: 0.03% Susceptible people: women Mode of infection: non-infectious complication:

(two) pathogenesis
The premise of paraneoplastic breast cancer is that the accessory breast must have breast gland tissue, and there is only a nipple or areola, or both have no glandular accessory breasts that can not produce paracancerous breast cancer due to the presence of the glandular gland. During the menstrual period, during the physiological changes such as pregnancy and lactation, there may be pain in the corresponding area and the breast, and even lactation with the lactation of the breast. Therefore, the accessory breast of the gland is the same as the breast of the normal part. The possibility of breast cancer.
1. The onset of breast cancer can occur in any part of the axillary to groin "milk line", but it is most common in the vicinity of the breast outside the axilla, accounting for almost 90%.
2. The pathological sub-mammary gland of the mammary gland is incompletely developed, and its pathological structure and characteristics are not significantly different from those of normal breast. Therefore, its pathological type is the same as that of breast cancer.
Prevention
Breast cancer prevention
1, more sun exposure is not easy to suffer from breast cancer medical research has proved that the body's vitamin D supplementation can reduce the incidence of breast cancer, and sun or daily diet can help the body to consume vitamin D. However, a recent study by French scientists shows that in the absence of sun exposure, relying solely on vitamin D supplements does not reduce the risk of breast cancer in postmenopausal women. The researchers found that women with more vitamin D had a 32% lower risk of breast cancer than women who had less vitamin D supplementation in areas with the strongest UV exposure.
2. At the same time, the results of the study showed that the vitamin D taken from the diet and the vitamin D obtained from the sun exposure will achieve the effect of preventing breast cancer according to a certain threshold ratio. However, the researchers said that menopausal women living in the northern latitudes are more difficult to achieve this threshold intake ratio, because the sun exposure in the northern latitude is limited, it is difficult to produce enough vitamin D to prevent breast cancer.
Complication
Paramilk breast cancer complications Complication
1. Eczema is an inflammatory reaction of the skin caused by a variety of complex internal and external factors with pleomorphic lesions and tendency to exude. Conscious symptoms are itchy. The condition is easy to repeat.
2, pain accompanied by shoulder and back, chest pain.
3. Functionally restricted tumors affect muscle tissue and can cause upper limb function and affect upper limb activity.
4. Infection secondary infection is also one of the more common complications of cancer.
Symptom
Paramilk breast cancer symptoms common symptoms limb swelling
The course of the disease varies from several months to several decades. It is more common in the axillary gland of the armpit. The left side is slightly more, mostly at the lateral edge of the pectoralis major muscle. Other parts are rare. Most of the masses are like peanuts. The larger ones are like walnuts. Hard, active, unclear perimeter, the surface of the tumor is generally smooth, a few can be adhered to the skin or the base, the skin is also "orange peel-like" change or ulceration, local pain can occur and often radiate to the chest and affected upper limbs, swollen The substance is swollen during menstruation or pregnancy and has painful swelling. The axillary lymph nodes can be swollen.
Examine
Examination of breast cancer
Acupuncture cytology can be found in breast cancer cells, and glandular lobular structures or intraductal carcinomas can be seen around the cancer cells.
1. X-ray examination of the mammography shows dense shadows in the secondary mammary gland (Fig. 1).
2. B-ultrasound found that with breast cancer, can help diagnose.
Diagnosis
Diagnosis and diagnosis of breast cancer
diagnosis
Due to the special location of the accessory breast, the diagnosis of the disease must meet the following conditions:
1. Before the sacral area, the subclavian cancer, clinical and histological must be found in the breast tissue that is not associated with the normal site of the breast can be diagnosed with para-breast cancer.
2. When the histological examination of the axillary mass is cancer, the glandular lobular structure or intraductal cancer image must be seen around the cancer tissue to exclude metastasis.
3. The normal part of the breast is not cancerous, or associated with cancer of different histological types.
Differential diagnosis
The disease must be distinguished from breast cancer and axillary lymph nodes.
