Your body is made up of cells. Usually, these cells grow, divide, and eventually die, making room for new ones. But sometimes, some cells start to change in a bad way. Instead of dying, they grow and multiply too much, forming a lump called a tumour.

Tumours can be two types: one that is not harmful (benign) and another that is harmful (malignant or cancerous). The dangerous tumours can attack and damage the healthy parts of your body. Moreover, they can spread to other places in the body, creating new tumours there. This spreading is called metastasis, and it’s a sign that the cancer has reached an advanced stage.

Stage 0: At this stage, cancer is still in the place where it started and hasn’t spread to nearby tissues. Stage 0 cancers can often be cured.

Stage I: This stage usually means there is a small tumour or cancer that hasn’t deeply grown into nearby tissues. It’s also known as early-stage cancer.

Stages II and III: In these stages, the cancers or tumours are larger and have grown more deeply into nearby tissues. They may have also spread to nearby lymph nodes, but haven’t reached other organs or parts of the body.

Stage IV: Cancer in this stage spreads to other organs or parts of the body. It’s sometimes called advanced or metastatic cancer.

Cancer can show different signs and symptoms depending on where it is in the body and how big it has become. Some common signs can be:

• Losing weight without any clear reason
• Having a fever that doesn’t go away
• Feeling very tired and weak
• Changes in your skin’s appearance
• Experiencing changes in your bowel habits or difficulty with urination
• Sores that take a long time to heal
• Noticing unusual bleeding or strange discharges from the body
• Feeling a lump or thickening in a part of your body, like a breast
• Having trouble swallowing or having indigestion
• A persistent cough or hoarseness in your voice

It’s important to remember that these signs can be caused by various reasons, not just cancer. To find out the exact cause of these symptoms, it’s essential to visit your doctor for proper evaluation and diagnosis.

Whether a person can be completely cured of cancer depends on various things like what type of cancer they have, how far it has grown (the stage), the available treatment options, and other factors. Different cancers have different chances of being cured.

It’s essential to understand that there’s no one-size-fits-all cure for cancer. Each type of cancer requires its own specific treatment plan.
