Of primary importance to stage determination and regional lymph node involvement is identification and analysis of the sentinel lymph node.
Any depth or size of tumor associated with regional lymph node involvement
Stage I and stage II have no involvement of the regional lymph nodes and are thus localized to the site of origin.
Mediastinoscopy allows a physician to observe and extract a sample from the nodes for further study. Involvement of these lymph nodes indicates diagnosis and stages of lung cancer.
Questions related to which patients should have resection of regional lymph nodes have led to an intermediary procedure known as sentinel node mapping and biopsy.
tumor is present with palpable regional lymph nodes and no metastases
Once the diagnosis is obtained, careful examination of the patient for regional lymph node involvement should be done. A careful review to uncover any symptoms of widespread disease is also appropriate.
Lymphadenitis
Tumor is present with palpable regional lymph nodes and no metastases. Medical Terminology answer.
Lymph channels-- The vessels that transport lymph throughout the body. Lymph is a clear fluid that contains cells important in forming antibodies that fight infection.
The lymph system, including lymph nodes and lymph vessels.
This procedure often involves removal of the regional lymph nodes as well.
Breast cancer staging is based on the size of the tumor, the involvement of lymph nodes and the presence of metastasis (spreading). It can't just be determined by the size until the other factors are evaluated as well. The presence of lymph node involvement is determined at surgery. Surgery should be scheduled within 4 weeks of detecting a tumor
