1.3 Abnormal Mitosis & Cancer
Types of Tumours
A group of abnormal cells that form lumps or growths
Benign Tumour
A mass of cells that are not able to invade neighbouring tissue or metasize. They have no symptoms or health consequences (the body is still able to function like normal). They are slower growing.
Malignant Tumour
A mass of cells that are able to invade neighbouring tissue or metastatize. They will show symptoms because they are pressing on neighbouring muscles and nerves. They are faster growing.
Tumour
Cancer
A group of diseases involving cell growth at an abnormal rate that has the potential to spread to other parts of the body.
Cancer
Cancer Cell
A cell whose DNA has been mutated, causing mitosis to happen unregulated, even when new cells are not need.
Healthy Cell
A cell whose DNA has been mutated, causing mitosis to happen unregulated, even when new cells are not need.
Metastasize
It happens when pieces of the tumour spread to other parts of the body, through the bloodstream or lymph.
Curing Cancer
Chemotherapy is the use of drugs to either cure, shrink or lessen the pain that comes with having cancer.
Chemotherapy
There are various ways that cancer patients can undergo in order to get rid of cancer cells.
Treatment
Radiation
Radiation works by killing cancer cells or shrinking them using high doses of radiation.
What Causes Cancer
Carcinogen
Environmental factors that increase the likelihood of a mutation in a cell.
Mutation
A change that disrupts the DNA sequence, causing abnormal cell activity.
Inheritance
DNA inherited from ancestors that may contain genes that increase the risk of attaining certain cancers.
