At the instigation of the Aeras convention -Insuring and borrowing with an aggravated health risk - and the 2014- 2019 Cancer Plan, the Law of 26 January 2016 introduces the « right to be forgotten » for people with cancer. Thus, people wishing to take out an insurance policy for a mortgage or consumer credit do not have to declare their cancer 10 years after the end of the therapeutic protocol, in the absence of relapse. This period is reduced to 5 years for cancers occurring before the age of 18 years. Associated with this right, the « reference grid » identifies situations for which insurance will be granted without surcharge or exclusion of guarantee, or under conditions that are close to standard conditions. This concerns both cancer -breast, thyroid, prostate cancers ...- and noncancer diseases -HIV, hepatitis C, cystic fibrosis ...-. Through his relationship with his patient, the doctor plays a key role in providing the best insight and helping him in his efforts.
