   Neither sentinel lymph node biopsy nor other diagnostic tests should be performed to evaluate early, thin melanoma, including melanoma in situ, T1a melanoma or T1b melanoma ≤ 0.5mm. [114] People with these conditions are unlikely to have the cancer spread to their lymph nodes or anywhere else and have a 5-year survival rate of 97%. [ 114 ]

   In addition to melanoma, individuals with the condition are at increased risk for pancreatic cancer. The diagnosis of dysplastic nevus syndrome is based on clinical presentation and family history. Treatment consists of resection of malignant skin lesions (melanoma).

5. Sentinel lymph node - Wikipedia

   The concept of the sentinel lymph node is important because of the advent of the sentinel lymph node biopsy technique, also known as a sentinel node procedure.This technique is used in the staging of certain types of cancer to see if they have spread to any lymph nodes, since lymph node metastasis is one of the most important prognostic signs.

6. Lymphadenopathy - Wikipedia

   Fine-needle aspiration cytology (FNAC) has sensitivity and specificity percentages of 81% and 100%, respectively, in the histopathology of malignant cervical lymphadenopathy. [27] PET-CT has proven to be helpful in identifying occult primary carcinomas of the head and neck, especially when applied as a guiding tool prior to panendoscopy, and ...

7. Micrometastasis - Wikipedia

   en.wikipedia.org/wiki/Micrometastasis

   Although surgeons are able to remove parts of a single lymph node from the body to screen, it is impossible to remove every lymph node and other organs (lungs, liver, bones, etc.) to look for spread. [2] Doctors must assume that the tumor cells have likely spread to other regions of the body if micrometastases are present in one of the lymph nodes.
