Your body is composed of numerous sorts of cells. Normal cell growth, division, aging, and death occur. The majority of the time, fresh cells take their place. However, occasionally, mutations cause cells to expand uncontrollably and form a bulk, or tumour, rather than dying.

Benign (noncancerous) or malignant (cancerous) tumours are also possible. Your body’s tissues can be attacked and killed by cancerous tumours. Additionally, they may proliferate and result in the formation of additional tumours in other body parts. This phenomenon, known as metastasis, is an indication of late-stage cancer.

Indeed. Your doctor may declare a cancer to be in remission when the treatment seems to be having an effect. A partial remission happens when the cancer gets smaller but still there. A full remission indicates that the malignancy is completely gone. A cancer’s likelihood of returning decreases with the length of time it is in complete remission, and eventually your doctor may declare the disease to be cured.

There are four standard stages of cancer: I through IV (1 through 4). In certain cases, a cancer’s stage is even zero.

The following describes these stages:
Stage 0: This stage indicates that the cancer has not migrated to neighbouring tissues and is still detected where it first appeared. Cancers in stage 0 are frequently cured.
Stage I: A tiny tumour or cancer that hasn’t spread far into neighbouring tissues is typically represented by this stage. It is also referred to as early-stage cancer.
Stages II and III: These stages typically indicate more advanced malignancies or tumours that have pushed more into the surrounding tissues. It’s possible that they also reached lymph nodes. They haven’t, however, spread to any other organs or bodily parts.
Stage IV: Cancer in this stage has spread to other organs or parts of the body. It may be referred to as metastatic or advanced cancer.

Not always, but occasionally. The location and size of the malignancy will determine its indications and symptoms.

A cancer may press against surrounding organs and other structures as it spreads. The pressure that results may manifest as symptoms.

Certain cancers grow in locations where they won’t show any symptoms or signs until they are quite advanced. For instance, unless the cancer spreads to the point where it presses against other structures and causes pain or jaundice, or yellowing of the skin, symptoms are usually absent from pancreatic cancer patients.
