Welcome @nadakhaled, that must be hard to learn that your father has been diagnosed with chronic lymphocytic leukemia (CLL). Many people live a long time with CLL. Often treatment for CLL, especially for early stage when there are no symptoms, is active surveillance or watchful waiting. Will your father receive watchful waiting or other treatment?

You may also wish to connect with other members who have experience with CLL in this related discussion:
