After five weeks of radiation and chemotherapy treatments for brain cancer, Sen. Edward Kennedy is recovering well, said his wife Wednesday in an e-mail sent to family members and friends. Vicky Kennedy said her spouse had been working out every day before heading to Boston, at Massachusetts General Hospital, in order to undergo a treatment. By afternoon, he will return at his family's compound in Hyannis Port.

The Associated Press acquired the e-mail on Monday, from a friend of the Kennedy family.

In the middle of May, the 76-year-old senator experienced a seizure at his home and was consequently diagnosed with malignant brain tumor. On June 2 he underwent surgery to eliminate the tumor. Despite the fact that the surgical procedure was said to be a success, his future scenario remains imprecise as he copes with radiation and chemotherapy treatment.

The only negative consequence is “fatigue”, says Vicky Kennedy. “That word has never been in Teddy's vocabulary before.” According to her, the senator is dealing with cancer with determination, doing all that it stands in his power to recover, to regain his forces. He keeps staying in touch “with his office staff and colleagues and still pushing all the issues he cares about.”

Kennedy's office has refused to talk about his treatment, even though doctors who were not in charge of his care said the typical chemotherapy for brain tumors was a pill known as temozolomide, which decelerated the growth and prevented cancer cells from spreading in the body. Radiation therapy, usually administered five days a week, would engage the use of a beam directed at the cancerous zone.
