The Crazy Hats charity will donate more than £160,000 to hospitals in Kettering and Northampton during Breast Cancer Awareness Month.
The Wellingborough charity has pledged more than £80,000 to each hospital to pay for new equipment and facilities.
Charity founder Glennis Hooper said: “In total we are giving about £160,000 to Northampton and Kettering general hospitals.
“None of us know who’s going to be next.
“As a charity we are dedicated to keeping the level of support going in the county. The public say they like what we do because it’s local and they know it’s going to benefit their loved ones.”
Miss Hooper set up the charity 10 years ago after her own battle with the disease.
During the past decade the appeal has raised more than £1m for hospitals and breast cancer support in the county.
It provides help to men and women before and during breast cancer treatment and supports them in their battle to become breast cancer survivors.
The charity also works closely with Kettering and Northampton general hospitals and the plastic surgery department at Leicester Royal Infirmary to provide support and help raise funds.
Throughout October events are being held across the county in aid of the charity to mark Breast Cancer Awareness Month.
A total of £1,095 was donated when the charity held a stall in Kettering town centre on Saturday.
Crazy Hats stalls will also be held in Corby town centre on Saturday, October 13, and at the Swansgate Centre in Wellingborough on Friday, October 19.
People are also doing their bit to raise money for the charity during Breast Cancer Awareness Month.
The Nifty 50 group, which meets at Redwell Leisure Centre in Wellingborough, St Ninian’s Church in Corby and pupils from Sir Christopher Hatton School in Wellingborough will take part in pink days this month.
A new Crazy Hats badge has also been launched after three schoolchildren won a competition to design it.
