Adenocarcinoma has four stages, with stage zero being the least dangerous. In the early stages, surgery can remove the cancerous cells, but as it progresses, chemotherapy and radiation may be necessary. Regular check-ups can lead to early detection.
There are four basic stages of adenocarcinoma, although some doctors recognize stage zero as well. In the early stages of this form of cancer, the tumor is isolated to one region of the body. As the disease progresses, lymph nodes and surrounding tissue may become involved. In the later stages of adenocarcinoma, the cancer can spread throughout the body until surgery can no longer remove the cancerous cells and chemotherapy or radiation treatments become necessary. Any specific questions or concerns about the different stages of adenocarcinoma and the appropriate treatment options for an individual situation should be discussed with a doctor or other medical professional.
Stage zero is considered the least dangerous of all stages of adenocarcinoma. At this stage, the cancerous cells have been located, but have not started growing enough to spread outside their original location. This is the easiest form of cancer to treat, and surgical removal of the cancerous tissue usually eliminates the disease completely. Some doctors consider stage zero precancerous and do not include it in the list of adenocarcinoma stages.
Adenocarcinoma tumors that are diagnosed in stage one are usually treated through surgery. This cancerous growth is still isolated to one part of the body, although it can extend into more than one layer of tissue. In most cases, all of the cancer cells can be removed through a single surgical procedure.
The next two stages of adenocarcinoma become a little more difficult to treat. In the second stage, the cancer has begun to spread to surrounding tissues and organs and may involve one or more lymph nodes. Surgery may be attempted in some cases, although additional treatment methods, such as radiation or chemotherapy, may also be used. The only real difference between these stages of adenocarcinoma is the extent to which the cancer has spread.
The last and most dangerous of the stages of adenocarcinoma is the fourth stage. By the time the cancer has reached this stage, the disease has spread to more areas of the body. Several lymph nodes may be affected and surgery is no longer considered a viable treatment option. Chemotherapy and radiation therapy can be used alone or in combination with each other in an attempt to control the disease process, although this phase often proves fatal. Regular visits to a doctor can often lead to early detection of the tumor so that it can be removed without the risk of death.
