Thus invasive ductal carcinoma, the most common form of breast cancer, is adenocarcinoma but does not use the term in its name—however, esophageal adenocarcinoma does to distinguish it from the other common type of esophageal cancer, esophageal squamous cell carcinoma. Several of the most common forms of cancer are adenocarcinomas, and the ...
Males with pure embryonal carcinoma tend to have a normal amount of the protein alpha-fetoprotein in the fluid component of their blood. The finding of elevated amounts of alpha-fetoprotein is more suggestive of a mixed germ cell tumour, with the alpha-fetoprotein being released by the yolk sac tumour component.
In the late 1960s through 1971 a cluster of young women, from their teens into their twenties, was mysteriously diagnosed with clear-cell adenocarcinoma (CCA), a cancer not generally found in women until after menopause. Doctors at Massachusetts General Hospital eventually linked DES exposure before birth to the development of CCA in these ...
Vaginal cancer is an extraordinarily rare form of cancer that develops in the tissue of the vagina. [1] Primary vaginal cancer originates from the vaginal tissue – most frequently squamous cell carcinoma, but primary vaginal adenocarcinoma, sarcoma, and melanoma have also been reported [2] – while secondary vaginal cancer involves the metastasis of a cancer that originated in a different ...
In women in whom pregnancy is a possibility, BHCG level can be measured during the diagnosis process. Serum alpha-fetoprotein , neuron-specific enolase , and lactate dehydrogenase can be measured in young girls and adolescents with suspected ovarian tumors as younger women with ovarian cancer are more likely to have malignant germ cell tumors.
This means that if breast cancer metastasizes to the lungs, the secondary tumor is made up of abnormal breast cells, not of abnormal lung cells. The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M".
Cancer of unknown primary origin (CUP) is a cancer that is determined to be at the metastatic stage at the time of diagnosis, but a primary tumor cannot be identified. A diagnosis of CUP requires a clinical picture consistent with metastatic disease and one or more biopsy results inconsistent with a tumor cancer.
Only a few women with GTD have poor prognosis metastatic gestational trophoblastic disease. Their treatment usually includes chemotherapy. Radiotherapy can also be given to places where the cancer has spread, e.g. the brain. [31] Women who undergo chemotherapy are advised not to conceive for one year after completion of treatment.
