Cancer is not a disease that appears suddenly; it is a process that begins secretly, when some cells begin to divide abnormally within the body. In most cases, the body sends early signals and warnings to try to draw our attention to an internal problem. But the problem is that most people ignore these signs or interpret them as simple and transient symptoms. In fact, early recognition of warning signs can be the difference between easy treatment and complete recovery, and the progression of the disease and difficulty controlling it.
In this article, we will learn about 20 warning signs that the body sends before the onset of cancer.
First: General signs that indicate an internal risk

1 Sudden and unexplained weight loss:
When a person loses more than 5 kg in a short period without dieting, this may indicate a metabolic disorder due to the activity of cancerous cells.
2 Chronic fatigue:
Feeling constantly tired even after sleep and rest can be a result of cancerous cells consuming the body’s energy.
3 Persistent fever:
A slight increase in body temperature for extended periods may indicate abnormal activity in the immune system.
4 Excessive night sweats:
Sweating during sleep without a clear reason may be an early sign of leukemia or lymphoma.
Second: Skin and visible signs
