Are you an everyday superhero?
If you can face cancer and win, you will likely be physically, emotionally, and mentally exhausted. But you will be better skilled and equipped to face tasks in the future which challenge you physically, emotionally, and mentally.
In this way you can turn the supposed weakness from cancer into a strength. The right employer will recognize this strength in you, even if you are still undergoing cancer treatment. Or perhaps you can leverage the lessons into being self-employed.
Maybe you can even use your experiences to become part of the body of people who work to spread information about cancer awareness and help other people, freshly diagnosed with cancer, to navigate the upcoming turbulent times. Nearly everyone can use such assistance.
Cancer may technically be considered a disability, but for you, it can be turned into an asset.
