Some patients are more worried, and consult in the background: among so many kinds of cancer, which one will metastasize the fastest? I am afraid that my cancer is the kind that is easy to metastasize.
1. Different transfer methods, the transfer speed is fast or slow!
1.Lymphatic metastasis:Lymphatic metastasis refers to the process in which malignant tumor cells enter the lymphatic vessels, reach the lymph nodes with the flow of lymphatic fluid, and grow within the lymph nodes to form metastases. The speed and extent of this type of metastasis depends on a variety of factors, including the type of cancer, the malignancy of the cancer cells, the structure and distribution of lymphatic vessels, and more.
Lymphatic metastasis usually occurs during the progressive stage of cancer, when the primary tumor grows to a certain extent, the cancer cells invade the surrounding lymphatic vessels and then spread to the lymph nodes. The speed and extent of lymph node metastasis varies depending on the type of cancer, and some cancer types are more likely to metastasize through the lymphatic tracts, such as breast, lung, and stomach cancers.
2.Implant transfer:Implant metastasis is a special modality of cancer metastasis that occurs mainly in cancers of organs within the body cavity. Implant metastasis occurs when cancer cells break away from the primary tumor site and implant on the surface of other organs or tissues within the body cavity. This metastasis is commonly found in cancers in body cavities such as the abdomen, chest, and pelvis, such as ovarian cancer, stomach cancer, and bowel cancer.
2. The type of cancer that metastasizes the fastest
Nonchorioepithelial carcinoma (choriocarcinoma):It usually occurs during or after pregnancy in women and is caused by malignant transformation of trophoblast cells. Choriocarcinoma cells grow extremely quickly and are highly aggressive, easily metastasizing through the bloodstream to other organs, especially the lungs, ** and brain. As a result, choriocarcinoma usually requires urgent**, including chemotherapy and radiotherapy, to control the spread of cancer cells as much as possible.
3. The "lying flat" in the cancer community
Basal cell carcinoma and verrucous carcinoma:These two cancers are considered to be relatively stable types in the cancer community. Basal cell carcinoma occurs primarily in the superficial layer, usually grows slowly, and rarely metastasizes to other sites. It usually appears as a round or raised bump that can sometimes form an ulcer. Verrucous carcinoma is also a low-grade malignant ** cancer, usually appearing as a wart-like or cauliflower-shaped growth. Because these cancers grow at a slower rate and have a lower risk of metastasis, they may be considered "lying flat," the relatively indolent type of cancer, in some cases.
