One in five NHS bodies in England is limiting the number of reconstructive surgeries that are allowed to patients with breast cancer, which could affect hundreds of women, a charity report suggests.
Breast Cancer Now says restrictions are "arbitrary" quality of life at risk.
But he found evidence that some procedures were being denied.
Breast surgeons have also expressed concern and ask for equal access to services.
Jo Waterman of Somerset says he is "frustrated and disappointed" to have to request funds to reduce the size of his healthy breast after he was diagnosed with breast cancer in May 2017.
They did a lumpectomy that allowed her to keep breast tissue and nipple, but left her breasts unbalanced.
"I do not want breast cancer to be the first thing I see when I look in the mirror," he says.
"People were telling me the most important thing is that you are still her and you have returned to normal, but I have not returned to normal
" I will not ruin my life by not having surgery, but if not encourage women to apply, they will be tested. "Off, and the few applications that the NHS receives for this type of surgery means that they will say there is no demand."
She adds: "I just want to get on with life."
"Women with breast cancer have gone through enough without having to go through another hurdle later."
Clinical guidelines indicate that patients should be able to return for breast reconstruction surgery at any time after initial treatment.
This may include inserting an implant or recreating the breast form with tissue from another part of the body.
If necessary, balance surgery is also recommended, which changes the shape of the remaining breast so that the breasts are symmetrical.
But the data obtained by the organization found that 47 of 208 clinical start-up groups (CCGs) in England had current policies that restricted these services, either by setting a time limit for them, limiting the number of surgeries allowed or denying access to balance surgery.
Nine other CCGs indicated that they could introduce similar policies.

Breast Cancer Now said that about one third of women who undergo a mastectomy every year in England choose to have a breast reconstruction, about 3,500, immediately or after a delay.
Estimate that hundreds of these women rushed to decide on surgery or were denied the corrective surgeries they need.
The report requires that all patients be allowed to return to breast reconstruction surgery at any time after diagnosis and treatment.
Baroness Delyth Morgan, executive director of Breast Cancer Now, said: "Reconstructive surgery has profound benefits for those who choose it, helping many to regain their confidence and their lives after breast cancer."
they represent a step back and are not at all in the best interest of patients. "
Mark Sibbering, president of the Breast Surgery Association, said the report showed that "in some areas access to this important part of breast cancer management is being restricted."
Samia al Qadhi of Breast Cancer Care said the decisions to restrict surgery were "atrocious" and "myopic".
"Wome n tell us every day that the long-term impact of surgery to eliminate cancer is more than physical, your self-esteem can be shattered.
" Breast reconstruction is, for many, an essential part of life with confidence after breast cancer, so we can not and should not let it get out of reach. "
