Former Australia captain Ian Chappell has been undergoing radiotherapy after being diagnosed with skin cancer, he has revealed.

The 75-year-old confirmed he had been through five weeks of intense treatment with cancerous cells removed from his neck, shoulder and underarm.

Chappell said the pathology has come back clear, while he expects to be able to commentate for Channel Nine during Australia's upcoming Ashes series in England, which begins on August 1.

"I didn't tell too many people early on," said Chappell, who also revealed he had suffered from skin cancers previously.

"Mainly because I just wasn't sure what the radiotherapy would involve and how weary I'd be.

"But as it turned out, it wasn't so bad. A bit of tiredness at night and a bit of skin irritation, but other than that I'm feeling pretty good.

"With the Ashes coming up now, I'll speak to Nine and just say, 'look, I'm ready to go if you need me.'"

Chappell enjoyed an international career spanning 16 years, scoring 5,345 runs in 75 Tests for Australia as well as featuring in 16 ODIs.
