The stage of a cancer is a measure of the extent to which a cancer has spread in the body. Staging involves evaluation of a cancer's size and its penetration into surrounding tissue as well as the presence or absence of metastases in the lymph nodes or other organs. Staging is important for determining how a particular cancer should be treated, since lung-cancer therapies are geared toward specific stages. Staging of a cancer also is critical in estimating the prognosis of a given patient, with higher-stage cancers generally having a worse prognosis than lower-stage cancers.
Cirrhosis happens in response to damage to your liver. Each time your liver is damaged, it tries to repair itself and in the process a scar tissue forms. According to Mayo Clinic , the liver damage done by cirrhosis generally can’t be undone. But if liver cirrhosis is diagnosed early and the cause is treated, further damage can be limited and, rarely, reversed. In your case the cirrhosis is in its early stages and you didn’t experience any serious symptoms so I think it should encourage you in your efforts to avoid bad habits that damage your liver and take a good care of it.
