It’s not clear what causes ovarian cancer, though doctors have identified factors that can increase the risk of the disease, said the Mayo Clinic.
The health site continued: “In general, cancer begins when a cell develops errors (mutations) in its DNA.
“The mutations tell the cell to grow and multiply quickly, creating a mass (tumour) of abnormal cells.
“The abnormal cells continue living when healthy cells would die.
“They can invade nearby tissues and break off from an initial tumour to spread elsewhere in the body (metastasize).”
