Canadian Pharmacies Encouraged By Cancer Survivors Delivering Normal Children Study

Cancer does not spare the youth, but encouraging news of negligible higher birth-defect risks in parents having undergone cancer treatment is welcome. Canadian pharmacies followed a US and Canadian study dispelling doubts about aftereffects of radiation and chemotherapy.

Results of the study published in the Journal of Clinical Oncology revealed radiation directed towards areas connected with childbirth such as testicles or ovaries did not cause long-term effects on sperm cells or DNA. Experts did have concerns about aftereffects due to evidence gathered from earlier treatment results leading to complications in a young girl’s uterus.

Cancer survivors are likely to have different side effects depending on strength of the treatment undertaken. For example, children born to such survivors grow infertile, may have low birth weight, or may have greater risk of miscarriage. People often buy Fludara, a chemotherapy drug, from Canadian pharmacies for the treatment of chronic lymphocytic leukemia.

The International Epidemiology Institute in Rockville, Maryland has already recorded cases of varying health concerns in children born of cancer survivors. In context, the recent study conducted surveys on a volunteer group consisting of over 20,000 childhood cancer survivors growing well into adulthood. Answers to questions about complications arising in childbirth were collected. Comparison was made to the type of radiation or chemotherapy drugs prescribed for cancer survivors against risk of having children born with birth defects.

Researchers compiled data on birth defects and related it to the risk babies had of developing birth defects in direct proportion to the amount of chemotherapy drugs, dosage, or intensity of radiation received by their parents as part of cancer treatment. Findings revealed 129 children amounting to approximately 3% developed one birth defect at the minimum when records collected over a period of five years from 4,700 babies born to cancer patients were analyzed.

Data collected from the 1970 and 1986 childhood cancer survivor study considered radiation or chemotherapy drugs prescribed to 57% lymphoma and leukemia cancer patients. Dosage did not have a considerable impact on children. For instance, 3% mothers surviving alkylating chemotherapy or radiation exposure gave birth to a child with at least one birth defect, while the percentage increased marginally to 3.5% in mothers who survived cancer without undertaking the same treatments.

Around 1.7% children born of fathers surviving cancer without radiation or chemotherapy were found to have birth defects, while the percentage increased to 1.9% in children born of cancer-surviving fathers having undergone chemotherapy or radiation as part of their treatment plans. Findings of the study clearly indicated there was no connection between treatment plans opted for cancer and higher risk of side effects as was earlier suspected.

Studies conducted in the past did indicate minimal risk involved in cancer procedures like chemotherapy, but they were not detailed enough in terms of specific side effects arising due to chemotherapy treatment focused on the ovaries and testes.

Canadian pharmacies are encouraged by the fact that chemotherapy drugs and radiation do not create complications. The study is likely to encourage pediatric oncologists create more awareness among young cancer patients about safety and efficacy of elaborate cancer treatment plans. Some concerns connected with reproduction of childhood cancer survivors are now addressed and should lead to more options without concern about side effects in the future.
