Diagnosis of cancer can be a life crisis for any person. Its impact varies with the type of cancer, treatment prospects and physical, emotional and social sources of the patient. Improvements in cancer treatment have enabled young persons with cancer to survive. A younger person faces the additional potential loss of reproductive function and the opportunity to have children.
The harmful effects of cancer therapy fertility can be temporary or permanent. Cancer treatment and their effects might include :
1. Surgery: Fertility can be affected by the surgical removal of uterus, ovaries and testis.
2. Chemotherapy: Maximum damage is done by drugs called alkylating agents. Younger women who receive chemotherapy are less likely to become infertile than older women.
3. Radiation: Radiotherapy can be more damaging than chemotherapy depending on the location and size of the radiation field and the dose given.High doses of radiation can destroy some or all of the eggs in the ovaries.
Other are hormones therapies for breast cancer. But its effects are often reversible.
Infertility as a result of cancer treatment can be psychologically upsetting for many patients and data suggests that those who pursued fertility preservation usually cope better with their cancer treatment.
The optional time for considering fertility preservation is before the initiation of any cancer treatment.
When to think about fertility preservation after the diagnosis?
A fertility specialist can help to preserve gametes, embryos and gonadal tissues before the treatment starts. Secondly, they will assist in using cryopreserved gametes and tissues for assisted reproduction.
Women who are about to undergo cancer treatment have various options when it comes to fertility preservation. For eg:
Men can also preserve their fertility before undergoing cancer treatment. For example:
1. Semen cryopreservation.This procedure involves freezing and storing semen at a fertility clinic or sperm bank for use at a later date. Samples are frozen and can be stored for years.
2. Radiation shielding: In this procedure, small lead shields are placed over the testicles to reduce the amount of radiation exposure they receive.
With continued research and clinical progress in this area, fertility preservation can be a safe, affordable and successful option for cancer survivors.
