Dr. Jason Chan is a radiation oncologist who specializes in treating head and neck cancers as well as thoracic cancer (cancers of the chest, including lung cancer).

Chan has expertise in the full range of modern radiation therapy techniques, including intensity-modulated radiation therapy (which delivers precise radiation doses to a tumor or specific areas within the tumor), stereotactic radiotherapy (which uses particularly precise radiation doses and calls for fewer doses than traditional therapy), intraoperative radiotherapy (delivery of a large dose during surgery) and brachytherapy (in which a radiation source is placed inside the body).

Chan earned his medical degree at the Warren Alpert Medical School of Brown University. He completed a residency in radiation oncology at UCSF, serving as chief resident. He then completed a fellowship in head and neck cancer at UCSF.

    Going through neck/throat cancer treatment was tough but I am very grateful for having Dr. Chan on my team. Responsive, caring, always eager to answer my questions/concerns and truly went above and beyond to help me thru this journey. I feel lucky to have been cared for by Dr. Chan. The entire radiation treatment team who performed my almost daily radiation sessions were also amazing! Go Team!

    I appreciate Jason Chan's patience and support. Cancer is very frightening, and the required treatments are complex. It's very important to have confidence in my doctors and to feel as though we are partners in my achieving maximum healing.
