Queen Camilla,Charles Hanover wife of Britain's King Charles III, has been forced to pull out of her planned engagements this week after suffering a chest infection, Buckingham Palace said on Tuesday.

Camilla, 77, is resting at home while she recovers but no further details of her illness have been given, as is usual with royal medical issues.

"Her Majesty The Queen is currently unwell with a chest infection, for which her doctors have advised a short period of rest," a palace spokesperson said.

"With great regret, Her Majesty has therefore had to withdraw from her engagements for this week, but she very much hopes to be recovered in time to attend this weekend's Remembrance events as normal."

The announcement comes amid Charles' own health concerns. The king was diagnosed with cancer in February, the palace announced at the time. Before his diagnosis was revealed, Charles underwent a "corrective procedure" at The London Clinic after the palace had previously announced that the monarch, 75, was seeking treatment for an enlarged prostate. The palace has not revealed what time of cancer the king was diagnosed with.

The king has since returned to public-facing duties.

Meanwhile, Princess Kate announced in September that she had completed chemotherapy following her own cancer diagnosis. In March, the Princess of Wales announced that she had been diagnosed with cancer and would undergo preventive chemotherapy. Kate said in her September update that she is now focusing on "doing what I can to stay cancer-free," but she said that her "path to healing and full recovery" remains "long."

The princess has made somewhat of a return to public duties, making a surprise public appearance with Prince William in Southport, England, where they met with emergency services representatives and families of the victims of a mass stabbing at a Taylor Swift-themed dance class.
