The chief executive officer of Goldman Sachs announced he has a "highly curable" cancer Tuesday. CEO Lloyd Blankfein said he has lymphoma in a message to clients and shareholders. He said he will receive chemotherapy treatment over the next few months in New York and will continue to lead Goldman Sachs.

"I will be able to work substantially as normal, leading the firm," he wrote. "I will, however, reduce some of my previously planned travel during the treatment period. I have discussed this approach with our Board of Directors and they are supportive."

Goldman Sachs was up 1.8 percent to $184.09 in premarket trading Monday. Below is Blankfein's full message to clients and shareholders:

"Late this summer after several weeks of not feeling well, I underwent a series of tests, which culminated in a biopsy last week. After the biopsy, I was told by my doctors that I have lymphoma. Fortunately, my form of lymphoma is highly curable, and my doctors' and my own expectation is that I will be cured.

"My treatment plan will include chemotherapy over the next several months in New York. My doctors have advised me that during the treatment, I will be able to work substantially as normal, leading the firm. I will, however, reduce some of my previously planned travel during the treatment period. I have discussed this approach with our Board of Directors and they are supportive.

There are many people who are dealing with cancer every day. I draw on their experiences as I begin my own. I have a lot of energy, and I'm anxious to begin the treatment. I appreciate your support and good wishes."
