Conservative MP Nick Boles revealed on Wednesday morning that doctors have found a "cancerous tumour" in his head.
In a series of tweets, the former skills minister said he would soon be starting treatment at King's College Hospital, London.
The Grantham and Stamford MP was diagnosed with Hodgkin's lymphoma in 2007 but soon recovered, and went on to win his seat in 2010.
Boles said he'd be taking a break from Twitter to focus on his recovery, but joked that parody account @GeneralBoles would keep his followers entertained.
Following his announcement, MPs from all parties started tweeting messages of support.
