There are no hard and fast rules. Generally, you don't have to tell an employer if you don't want to. Mostly it's up to you if and when you let people know.
You have important legal rights from the day you're diagnosed. These rights mean that employers shouldn't discriminate against you. You should also be able to ask for the support you need in the workplace.
What employers are allowed to ask
Under section 60 of the Equality Act, an employer is not usually allowed to ask health questions before offering you a job. The employer may ask if you need adjustments for a job interview or assessment.
They might also want you to fill out an equal opportunities form. This should be kept separate from the main application form by the human resources department.
Telling an employer
One of the advantages of being open with employers is that you have the right to equal treatment and you can ensure that this happens.
People with cancer automatically meet the definition of 'disabled' under the Equality Act (England, Wales, Scotland) or Disability Discrimination Act (Northern Ireland). This law covers areas of employment, including recruitment and contracts.
This means you're protected against discrimination if an employer rejects your job application because of cancer. They also have to make changes to help you do the job.
Having cancer might mean there are things in your CV or working life that need to be explained, like a gap in your education or career because you were unwell or had to retake an exam. It may help to explain the situation so everyone knows what happened.
Remember, your experiences are likely to make you a stronger candidate. Tell employers how you've managed your diagnosis and what you've learnt.
You may have developed greater determination, be able to manage stressful situations or build relationships with people.
Not telling an employer
You may have personal reasons for deciding not to tell an employer about your diagnosis. Having cancer is a very personal experience and you know best. You always have the right not to tell people if you don't want to.
However, if you don't tell an employer you're disabled, it may be harder to enforce your rights if they don't treat you fairly. It also takes the emphasis away from the employer having to make reasonable adjustments.
