BREAST CANCER BASE

Breast cancer and other tumors, often through the blood or lymphatic Road spread to other parts.
(1), lymph node metastasis : axillary lymph nodes and internal mammary lymph node metastasis of breast cancer is the No. 1 station. Breast cancer patients armpit lymph node metastasis in the high rate of clinical reports of patients with breast cancer is 50% to 70% have axillary lymph node metastases. Axillary lymph node metastasis and primary tumor size of the tumor size, the greater the rate of axillary lymph node metastasis, the higher transfer several more.
Intramammary lymph node metastasis and tumor and the stage of the disease. It was reported that the lesion in the lateral breast milk within its metastasis rate of 12 was 70.9%, lesions were located in its central transfer rate of 22%, lesions were located in the medial transfer rate of 21 was 70.9%. There axillary lymph node metastasis in patients its internal mammary lymph node metastasis rate also increased.
The supraclavicular lymph node breast lymphatic drainage of the two stations, mainly via the transfer of axillary lymph nodes or internal mammary lymph nodes, most of the ipsilateral and contralateral to be transferred to the supraclavicular lymph nodes.
Tumor cells can reverse way through the transfer of contralateral axillary or inguinal lymph nodes.
(2) hematogenous metastasis : breast cancer cells can be directly caused invasive vascular distant metastasis. The incidence of distant metastasis rate and the primary tumor size, lymph node metastasis, and the number of pathological classification. The most common distant metastasis to lung, bone Secondly, pleura, liver, brain and adrenal so. Although prone to breast cancer metastasis and hematogenous metastasis, but if effective control measures, it will effectively control their transfer. 

The International Union Against Cancer TNM staging of Law (1988) has been widely used in various tumors. TNM staging international law :

1) the primary tumor (T) phases :
Tx primary tumors of unknown (to be removed).
T0 primary tumor did not palpable.
Tis carcinoma in situ (including lobular carcinoma in situ and ductal carcinoma), Paget's disease confined to the nipple, the breast pieces and did not lay hands on.
T1 tumor diameter less than 2Cm.
T1a tumors in maximal diameter of 0.5cm below.
T1b tumors largest diameter 0.5 to 1cm.
T1c tumors largest Path 1 ~ 2cm.
T2 tumors largest Path 2 ~ 5crn.
T3 tumors more than 5 cm maximal diameter.
T4 tumors of any size, a direct violation of chest and skin.
T4a direct violation chest wall tumor.
T4b surface of the breast skin edema (including Orange kind edema), skin ulcer or skin surrounding the tumor nodules satellite, but not more than ipsilateral breast.
T4c including T4a and T4b.
T4d inflammatory breast cancer.

How breast cancer follow-up?
Follow-up interval : after two years : 3 to 6 months;

After three to five years : six months;

After more than five years : once a year.

Follow-up doctors

Follow-up : timely detection of recurrence and metastasis and timely treatment; Check contralateral breast; Adjuvant therapy; New drugs, new program evaluation.

What is the recurrence of breast cancer?

The spread of cancer cells, causing local recurrence and (or) distant metastasis;

1 / 3 of patients with breast cancer relapse will happen.
