Adenocarcinoma is a type of cancer that starts in glands that line the insides of the organs, which is why it can affect different body areas. The stage of adenocarcinoma depends on the size of the tumor and whether it has spread to other parts of the body. The stages of adenocarcinoma may differ depending on where the cancer is located, but the following guidance may help patients understand the general adenocarcinoma stages:

• Stage 0 adenocarcinoma: The cancer remains where it started and hasnt grown into nearby tissue.
• Stage 1 adenocarcinoma: The cancer is small and contained to local tissue, and has not spread to nearby lymph nodes or to other organs.
• Stage 2 adenocarcinoma: The cancer cells have more deeply spread into nearby tissue and possibly into local lymph nodes, but not to distant organs.
• Stage 3 adenocarcinoma: The tumor may be larger than in stage 2, or the cancer cells may be observed in deeper tissue or lymph nodes.
• Stage 4 adenocarcinoma: The cancer has spread to other parts of the body, such as the liver, lungs, or bones.

Its important to note that the survival rate of adenocarcinoma is highly dependent on the patient’s circumstances, including the stage of the cancer, its location, and the individuals overall health.
