Cancer develops due to abnormal cell growth and the division of cells. These cellular modifications result in a solid mass (tumour) made up of these abnormal cells. It's important to note that not all tumours are cancerous, they can either be benign or malignant.
As our knowledge of cancer increases, we become more capable of avoiding and defeating it. Therefore, investing in research about cancer has positive long-term implications.

Uncontrolled cell growth and cell division
BENIGN TUMORS
1. The tumour grows until it has used up all the space available to it. 2. Generally, tumours remain confined to the membrane and do not spread to other parts of the body. 3. Generally, this kind of tumour is not dangerous to health and it does not contain cancerous cells.
MALIGNANT TUMORS
1. Malignant tumours are dangerous and cancerous and they will grow if unchecked and invade neighbouring healthy tissues. 2. Cancerous cells can detach from their original spot in the body and spread to other areas through the bloodstream. This process is known as metastasis. 3.Cancerous cells spread to other healthy tissues and cause secondary tumours. Malignancy of these tumours is very risky, making them fatal at times. That's why malignant tumours are classified as cancers.
Risk factors of developing some cancers
Cancer can effect anyone, but possessing some risk factors does not guarantee its occurrence. It simply implies a greater susceptibility to the disease. Thanks to developments in medicine, cancer survival rates have improved drastically. From better treatment options to earlier diagnosis and more screening, it's clear that these advancements have been beneficial for many people.
Some lifestyle choices have been linked to the risk of developing certain types of cancer. Scientists have identified an array of lifestyle choices that can increase one's susceptibility to the disease.
🚭
It is a widely acknowledged fact that smoking is connected to lung cancer, but research has also found evidence of its link to many other types of cancer like mouth, bowel, stomach, and cervical cancer.
