Pregnancy after breast cancer: What an expert wants you to know


Breast cancer affects the lives of almost all Americans. One in eight women has received breast cancer The disease is endemic throughout life, making cancer the most common in the US Although most cases occur in those with postmenopausal, 19% of cases are with young, elderly women giving birth.

Because breast cancer patients who still want to raise their families, can be both stressful and stressful to deal with new approaches to the treatment and treatment of future and middle-birth birth anxiety.

As a reproductive electrician, I work with them cancer patients of course discuss what they can do to keep the please, so that every woman can achieve her marital goals. Fortunately, in the midst of the fight against this deadly, indiscriminate disease, there is hope for the future. We have a number of ways to help women with cancer improve their families.

Here is what I want women to know about childbirth and pregnancy after breast cancer.

It is unfortunate that during cancer treatment, chemotherapy can damage and eradicate a woman’s ovaries, making complications in the future more difficult. The risk of future childbirth for a cancer patient depends on the type and amount of treatment, as well as the age of the patient during treatment. And when you get cancer and get well, pregnancy it can be very difficult every year late, due to Birth effects on childbirth.

However, there are several ways to maintain your fertility before receiving treatment for breast cancer.

Fertilization after breast cancer

Cold egg

Egg cooling is the process by which mature eggs are removed from the eggs and refrigerated for future use. In order to freeze the eggs before they are treated for breast cancer, the mother takes injections to make eggs for 10 to 14 days.

Since most types of breast cancer are characterized by estrogen, and maternal estrogen levels often increase during pregnancy, the drug Letrozole can also be prescribed to reduce the body’s estrogen exposure over a long period of treatment.

When a woman decides to use frozen embryos in the future to fertilize, she is melted and fertilized to produce eggs, which she can transfer to the uterus and / or test genes.

This can start immediately and at any time during menstruation, so as not to delay the treatment of breast cancer. Most patients complete their rotation between breast surgery and chemo / radiation.

Cooling of eggs

Some women who have boyfriends choose to have a cold for the fetus before they get cancer. The first stage of the process is similar to the freezing of an egg, but after fertilization of the eggs and the return of the eggs, the sperm is used to make eggs to form eggs. These eggs grow in the laboratory and are usually frozen on the blastocyst (Day 5).

Blastocyst eggs can be tested for chromosomal defects, or even cancer-causing genes such as BRCA in women with a congenital cancer.

Uterity of the uterine muscles

Women who need to start receiving cancer treatment immediately and do not have time to cool down or an egg or immature baby also have a better chance of keeping skin.

Laparoscopic surgery is performed to remove one part of the ovary, and this tissue is divided into pieces and cooled later. Then when the mother is ready to try to conceive, a piece of the ovaries is melted and she undergoes surgery on an existing ovary. Some of the implants will also use hormones and later release eggs.

The procedure was considered experimental until recently, but today more than 130 babies are born worldwide from nerve implants.

Agnists and GnRH

In support of chemotherapy, drugs called GnRH agonists can be given to treat female hormones. This keeps the egg bag “silent” so that the eggs are not damaged too much. These drugs reduce the chances of menstruation during cancer but they are contradictory.

It does not replace the other fermentation methods mentioned above but may be offered in addition to these medications.

Pregnancy after breast cancer

Preparation for pregnancy after breast cancer

Deciding when to get pregnant after treatment for cancer is difficult and can affect many things. The type and stage of the cancer and the need for treatment both contribute to choosing the best time to give birth. It is always important for women to discuss this with their oncologist before they become pregnant.

In most cases, patients are advised to wait several years after completing treatment before trying to conceive. In some cases, if the cancer has an estrogen deficiency and short-term hormonal suppression is required, the advice may be a long wait.


For women with estrogen cancer, and / or women who take long-term hormones to reduce relapse, another option is to build their families with the help of a carrier, known as a midwife.

Embryos produced before cancer (or a fetus before fertilization) can be transferred to the uterus of a carrier, who is pregnant but has no other relationship with the baby. This method allows families to stay healthy, safe in women who may be at high risk of getting cancer during pregnancy.

Other ways to raise your family after cancer

Women who do not maintain their fertility before receiving cancer treatment also have other ways to raise their families. If she does not get pregnant on her own, she can use a fertilized egg or embryo to get pregnant, or she can have a baby.

Hope to marry in the future

New discoveries of breast cancer can create uncertainty and uncertainty about the future, especially for women with premature ejaculation who are hoping to raise their families.

Fortunately, women of childbearing age who are experiencing breast cancer have many ways to make their childhood dreams come true. My cold-blooded patients often say that this information is reliable and gives them strength during difficult times. What a privilege it is to care for each cancer patient carefully and to build a good family!
