Dear Agnes,
Any healing modality that involves being close to another should include a decision not to treat if one has any contagious illness. With other ilnesses, perhaps the practitioner should be realistic in regard to their own energy and health. (We can look at a cut & decide if it is healed but most other health conditions are not so easy to evaluate) Lowered immunity suggests that one refrain from Reiki for one's own benefit & healing.
We tend to think of healing as something that is finite but it is often an ongoing process.
I am not aware of any reason not to Reiki others if one is a cancer survivor. Actually, people who are ill generally benefit from exposure to those who have dealt with a health crisis, it gives them hope.
I would be honored to have you Reiki me as Im sure others would.
peace & joy,
holobon
