Conservative MP Chloe Smith has urged the public to "check for lumps" after revealing she has breast cancer.
The 38-year-old constitution and devolution minister revealed her diagnosis on Twitter on Monday.
"I've learnt I have breast cancer, & start treatment soon," she said.
"I aim to carry on as normally, positively & openly as possible - with a bit of support & privacy at times."
The MP for Norwich North urged people to check for lumps and "see your GP without delay if you find one".
"And you should continue to use the NHS, get your scans, turn up for your appointments and pick up your treatments."
Ms Smith has recently launched a campaign in her constituency for more doctors and dentists.
She had written to the housing secretary Robert Jenrick urging him to make sure there are "the right" health facilities built alongside the development of new homes.
She highlighted the "challenges" people have faced when arranging to see a doctor or dentist during this year.
The mother-of-two said: "I'm doing this because people need to be able to get appointments at the doctor or the dentist, now and in the future."
Some people across the UK have claimed they have struggled to make medical appointments during the pandemic.
Research by Macmillan Cancer Support revealed up to 50,000 people in the country have cancer that has not been diagnosed due to the impact of the coronavirus pandemic.
The study highlighted fears the figure could double to 100,000 if vital cancer health services are not fully restored throughout the UK.
