Reproductive Health in Breast Cancer Survivor

This study focuses on young women who have had breast cancer to understand how the illness and its treatments affect their reproductive health. With more women having breast cancer earlier in life and starting families later, it's important to understand these effects. The researchers will look at information from women aged 18 to 50 who were diagnosed with breast cancer between 2010 and 2018. They want to see how treatments might impact a woman's fertility (her ability to get pregnant) and the health of her children if she has them after treatment. The goal is to provide clearer information to patients and help doctors make better recommendations about fertility preservation and contraception.

What is this study about?

This study is about a very important topic for young women diagnosed with breast cancer: their ability to have children in the future and the health of those children. More and more women are being diagnosed with breast cancer at a younger age, sometimes before they've had a chance to start a family. At the same time, many people are choosing to have children later in life.

Treatments for breast cancer can sometimes affect a woman's fertility, making it harder to get pregnant. Doctors often talk about 'fertility preservation' options before treatment starts, which means taking steps to protect a woman's ability to have children later. This study aims to collect information on women who have gone through breast cancer to understand what happened regarding their fertility and if they had children, how healthy those children were. This information is key to making sure women get the best and most up-to-date advice.

The researchers hope that by looking at this information, they can give clearer guidance to patients and doctors. This means helping women understand their choices better and ensuring that fertility preservation and advice on family planning are offered more regularly to those who might benefit from them. They will compare information from women with breast cancer to women of a similar age who haven't had breast cancer, to get a better understanding of the situation.

Key takeaways

  • Looks at fertility and healthy babies after breast cancer.
  • Uses existing, anonymized medical records; no patient involvement needed.
  • Helps improve advice for young women with breast cancer.
  • Focuses on women aged 18-50 diagnosed between 2010-2018.
  • Aims to make fertility preservation and family planning advice better.

Who may be eligible?

To be included in this study, you would be a woman who was diagnosed with breast cancer when you were between 18 and 50 years old. Your breast cancer would have been estágio 1 to 3, meaning it hadn't spread widely throughout your body, and you would have been diagnosed between January 1, 2010, and December 31, 2018. You would also need to have received your treatment at one of the participating hospitals.

You would NOT be included in this study if your breast cancer had spread to distant parts of your body (estágio 4) at the time of diagnosis. Also, if you have previously told your hospital that you do not want your medical information used for research, then your data would not be included in this study. The study uses existing anonymous medical records, so you don't actually 'join' or do anything new yourself.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

  1. Were you between 18 and 50 years old when diagnosed with breast cancer?
  2. Was your breast cancer diagnosed between 2010 and 2018?
  3. Was your cancer stage 1, 2, or 3 (not stage 4 metastatic)?
  4. Did you receive treatment at a participating hospital?
  5. Have you NOT previously told your hospital you don't want your data used for research?
Answer every question to see your result.

What does participation involve?

This study is different from many others because you won't actively 'take part' or have to do anything. The researchers will be looking at existing medical records from women who have already been treated for breast cancer in the past. This means there are no extra appointments, no new tests, no medication to take, and no special follow-up visits involved for you. Your past medical information will be used anonymously, meaning your name or personal details won't be linked to the study findings.

Potential risks and benefits

There are no direct risks to you from participating in this study as your medical records are used anonymously and you won't have any direct involvement. The main benefit of this research is that it will help future generations of women diagnosed with breast cancer. By understanding the impact of treatments on fertility and the health of children born afterwards, doctors can provide better advice and support. You have the right to have your data withdrawn from this research at any time, should you wish to do so, by contacting the specific hospital where you were treated.
