Following are the different stages of stomach cancer and the treatment options.
Stage 0: Stomach cancer develops when cells with genetic abnormalities begin to proliferate at an excessively fast rate in the stomach's inner lining. When it comes to removing stage 0 stomach cancer, surgery is usually the best option. The surgeon may remove part or all of the stomach as well as the lymph nodes during this procedure.
Stage 1: The tumour has progressed to the lymph nodes and borders the inner wall of the stomach.It is treated in the same way that stage 0 is treated: surgery to remove part or all of the stomach, as well as any nearby lymph nodes.Chemoradiation can be administered before or after surgery to reduce the tumour or to kill any cancer cells that remain.
Stage 2: The tumour has already progressed from the stomach lining wall to deeper layers and, most likely, to surrounding lymph nodes in stage 2 stomach cancer. In this instance, chemo or chemoradiation is recommended before surgery.
Stage III A: The cancer has migrated to the stomach's deeper layers and maybe to surrounding lymph nodes. The main treatment is still surgery to remove half or all of your stomach, as well as adjacent lymph nodes. Before the procedure, you'll almost likely receive chemo or chemoradiation, and you may also undergo one thereafter.
Stage III B. The cancer may have spread to all layers of the stomach, as well as other organs such as the spleen or colon. It could be larger or smaller, but it will stretch deep into your lymph nodes.
Surgery to remove your entire stomach is frequently combined with chemo or chemoradiation. This can help you get rid of it in some cases If not, it can at the very least alleviate symptoms.
If surgery isn't a possibility, chemo, radiation, or a mix of the two may be used instead, depending on your body's capabilities.
Stage 4: Cancer has gone far and wide to organs such as the liver, lungs, and brain at this stage. It's far more difficult to treat, but your oncologist can help you control your symptoms and provide some comfort.
If a tumour clogs part of your GI system, you may have the following symptoms:
- An endoscope, a small tube that passes down your throat, is used to use a laser to remove a portion of the tumour.
- A stent is a small metal tube that maintains blood flow. One of these can form between the stomach and the oesophagus, or between the stomach and the small intestine.
- To build a path around the tumour, gastric bypass surgery is used.
- An operation to remove a portion of your stomach.
At this time, chemo, radiation, or both may be employed. You might also receive individualised treatment. These medications target cancer cells while leaving healthy cells alone, potentially resulting in fewer adverse effects.
