Lactation suppression medications are used to help reduce milk production.
Common lactation suppression methods include:
1.
Traditional Chinese herbal remedies: Prepare 120 grams of roasted barley malt, boil it in water, and take it in three doses (most suitable during the early postpartum period and before weaning).
Alternatively, prepare a bowl of soy milk, add a little sugar, mix well, and consume.
2.
High-dose Vitamin B6: The recommended dosage is 200 mg of Vitamin B6, taken in three divided doses daily.
After 48 hours, reduce the dosage to 100 mg, also in three divided doses, for a total duration of three days (most suitable before starting breastfeeding and during weaning).
3.
Estrogen-based medications such as Ethinyl Estradiol and Ethynyl Estradiol: These can be taken orally or injected, with a dosage of 5 mg each time, three times a day, for a continuous period of three to five days (most suitable one to two days postpartum, before significant milk secretion occurs).
4.
Other lactation suppression medications: Prepare 6 grams of Sichuan pepper, boil it in water, and add 60 grams of brown sugar; drink in divided doses for one to three days.
Alternatively, prepare 4 grams of senna leaves, soak them in 200 to 300 milliliters of boiling water for about ten minutes, and take in two to three divided doses daily for three to seven days.

The concern regarding lactation suppressants and their potential link to cancer is a topic that has generated considerable discussion and misinformation. To address your question, it is essential to clarify what lactation suppressants are, how they work, and the current understanding of their safety profile.

Lactation suppressants, often referred to as "milk suppression medications," are typically prescribed to women who wish to stop breastfeeding or to manage certain medical conditions. Common medications used for this purpose include bromocriptine and cabergoline, which are dopamine agonists. These medications work by inhibiting prolactin, the hormone responsible for milk production.
The fear that these medications could cause cancer primarily stems from the understanding of how hormones influence cancer development. For instance, certain cancers, such as breast cancer, are hormone-sensitive, meaning that their growth can be influenced by hormones like estrogen and prolactin. However, it is crucial to differentiate between correlation and causation.
Current research does not support the notion that lactation suppressants directly cause cancer. A review of the literature indicates that while there may be theoretical concerns regarding hormone levels and cancer risk, there is no substantial evidence linking the use of lactation suppressants to an increased risk of cancer. In fact, studies have shown that the use of these medications is generally safe when prescribed and monitored by a healthcare professional.

It is also important to consider the context in which these medications are used. For instance, women who choose to use lactation suppressants may have various underlying health conditions or personal circumstances that necessitate their use. The decision to use such medications should always involve a discussion with a healthcare provider, who can weigh the benefits against any potential risks based on individual health history.

Moreover, the fear surrounding lactation suppressants may be exacerbated by anecdotal reports and misinformation circulating on the internet. It is essential to approach such claims critically and seek information from reliable medical sources or professionals.
In conclusion, while it is understandable to have concerns about the safety of any medication, current evidence does not support the claim that lactation suppressants cause cancer. If you have specific concerns about your health or the use of these medications, it is advisable to consult with a healthcare provider who can provide personalized guidance based on your medical history and current health status. They can help you navigate your options and make informed decisions regarding lactation suppression and any associated risks.
