Incurable currently. Things may change tomorrow so, first of all, try to buy as many time as you can.

You need to collect more info about your disease before to take a decision. Disclosing it will tag you as unable to work anymore (when in fact you could just experience a minor decrease in your working capacity for a long time, depending on the disease). You may need allocate extra money to fight the disease. Therefore, one strategy could be to take support in your close circle or friends and family and keep the mouth shut for now in the rest of cases. If you feel strong enough emotional and physically to stand the job you may want to keep your income source and current life as many time as you can. Less changes will help to focus in the relevant parts and are better for the emotional aspect.

Alternatively, if the work don't has a special value for your identity, you hate it, or don't need the money, you may want instead to quit as soon as possible and spend more quality time with your family.
