Organisation: Cancer Flashcards
What may cause a tumour?
Changes in genes may lead to uncontrolled cell growth through mitosis this then may produce a tumour.
What are the two types of tumours?
The two types of tumours include benign (non-cancerous) and malignant (cancerous).
What are benign tumours?
Benign tumours are growths of abnormal cells which are found in ONLY one area. They are usually contained within one membrane and do not invade other parts of the body (they stay in one place).
Do benign tumours spread around the body?
Benign tumours do not spread around the body.
Do malignant tumours spread around the body?
Malignant tumours can spread around the body.
How do malignant tumours spread around the body if they are spreadable?
Malignant tumours spread when malignant cells invade neighbouring tissues and move into the blood stream, once in the blood stream, the malignant cells spread to different parts of the body and they form new tumours. (These new tumours are called secondary tumours)
Why does Radon increase the risk of getting cancer?
What is radon?
Radon is a radioactive gas which increases the risk of getting lung cancer as it releases ionising radiation which damages the DNA in our cells and this causes our cells to undergo uncontrolled cell division, leading to cancer.
What are the differences between benign and malignant tumours?
The differences between malignant and benign tumours are malignant tumours are cancerous and are able to spread where as benign tumours are non-cancerous and unable to spread.
