A woman who tested positive for the BRCA gene mutation has spoken to Daybreak about how checking her family medical history to see if she was at higher risk of breast and ovarian cancer affected her life.
Caroline Presho, 39, said the positive diagnosis "messes with your head" because it made her aware of a potential cancer timebomb.
However, opting to have her ovaries and fallopian tubes removed has given her the chance "to be here longer had I not known".
Women are less likely to survive ovarian cancer in the UK than in other comparable countries, researchers have said.
Differences in treatment for advanced ovarian cancer - which has low survival rates in the UK - could explain why the UK lags behind other countries, according to a study.
The study, published in Gynaecologic Oncology, found that in the UK 69% of women survived for at least one year, compared with 72% in Denmark and between 74% and 75% in Australia, Canada and Norway.
Lead author Dr Bernard Rachet said: "The results show that the proportion of women with advanced disease is similar to that in other countries, but that survival for women with advanced disease is much lower.
"This suggests that the success of treatment is lower in the UK, and more effort should be made to ensure that UK women with ovarian cancer have the same access to the best treatments."
