Sub.: Request for leave from work due to my illness

Dear Sir,

I am hereby applying for a leave from work for an indefinite period of time because of the serious nature of my sickness. I am sorry to inform you that I am suffering from lung cancer at stage II. My doctors have advised me to start getting the treatment immediately. Hence, I am going to be hospitalized from (date) onwards for treatment.

As you must be aware of such sickness takes a lot time for treatment and the chance of getting fully cured is also sadly a questionable thing. As such, I am not sure how long I am going to be on leave from work for this treatment.

Therefore, I kindly request you to approve my leave for an indefinite period of time. I will be keeping you updated on the progress from time to time if you don't mind. As soon as I get better and in a position to work I will join back at service.

Looking forward to your support at this juncture of my life.

Yours sincerely,

(Name of the Employee)
