A Good Morning Britain guest issued a warning to all woman aged 50 and above on Monday.

The daytime programme was back at the start of a new week, with presenters Susanna Reid and Ed Balls at the helm of the show. As ever they discussed the topics of the day, latest news, and were joined in the studio by a number of guests.

Professor Pat Price, founder of Radiotherapy4Life, appeared on GMB via video link in the wake of the Duchess of York's breast cancer diagnosis. A spokesman for the duchess said: "Sarah, Duchess of York was recently diagnosed with an early form of breast cancer detected at a routine mammogram screening.

"She was advised she needed to undergo surgery which has taken place successfully. The duchess is receiving the best medical care and her doctors have told her that the prognosis is good.

"She is now recuperating with her family. The duchess wants to express her immense gratitude to all the medical staff who have supported her in recent days.

"She is also hugely thankful to the staff involved in the mammogram which identified her illness, which was otherwise symptom free, and believes her experience underlines the importance of regular screening."

Professor Price also urged people to book their screenings. She told GMB viewers: "Women out there who have got their letters must go and book their mammogram. It saves lives.

"We know that 75% of tumours that are picked up this way are the earlier stage and are really curable. [And there is an] 80% ten-year survival.

"It is terribly important to go for screening. Early diagnosis saves lives".

The NHS said under its Breast Screening Programme, "eligible women will usually receive their first routine invitation for breast cancer screening between the ages of 50 and 53 and will normally be invited every three years until they are 70".
