我是最后一个知道避孕药会增加乳腺癌机率的人吗？

现在乳腺癌全球发病率高居cancer首位 和避孕药的广大使用有关系吗？

根据我妈妈主治医生分析，我妈妈乳瘤的成因：
1）只生了一个娃，乳汁未能充分释放，所以导致乳腺导管瘤。
2）长期口服避孕药。
所以古时候乳瘤发病率应该低很多。

那要问得了乳腺癌的人有没有长期服用避孕药? 不是说遗传因素占很大原因吗？

但避孕药会减低卵巢癌的几率

是的，说是可以降低卵巢癌和另外一个癌症 但是女性现在最高的两个癌症是乳腺癌和宫颈癌啊？ 所以我们应该预防的不是这两个癌症吗？
而这两个癌症恰恰又是避孕药可以增加机率的，这么巧的吗？ 对science不是很懂 但我觉得社会有一点抑制避孕药危害的信息了吧？

好像是最近的reaearch，我吃完夜宵一会儿贴上来 之前看breast cancer risk factor我以为是饮食、作息、基因、抽烟喝酒，所以也不知道是我对science理解不好，还是说社会不想让女性知道hormone based 避孕药的危害

激素分三层吧，
大脑部位的垂体，下丘脑，松果体， 脖子部位的甲状腺，甲状旁腺，胸腺， 胸腹部位的消化腺，性腺
越往上越等级越高，即便最低级的激素也有拮抗作用，而且都是非常少的量就足以牵一发而动全身的，为什么非要从分子级化学生物的角度死磕呢？而且一时半会儿都看不到尽头，就这样的半拉子研究结果，都用在了当下的小白鼠身上。就像一百年前肾上腺激素包治百病一样，这个路子，再来一百年，还是原地打转。

All types of hormonal birth control may increase breast cancer risk, study finds
Share on Pinterest
Progestin-only birth control pills are a common form of hormonal contraceptive, yet knowledge on their association with breast cancer risk was limited. In a new study, researchers investigated the link between hormonal contraceptive use and breast cancer risk. They found that progestin-only contraceptive use increases breast cancer risk similarly to combined contraceptive use. They say that physicians should weigh the benefits and risks to patients of hormonal contraceptive use. Experts say the findings are broadly in line with known risks, which overall are small. Between 2017 and 2019, around 65% of womenTrusted Source  aged 15- 49 used some sort of contraception, and 14% of them used the pill. Contraceptive pills come in two forms: the progestin-only pill and the combined pill containing both progestin and estrogen-based ingredients. Progestin, or progestogen, is a synthetic version of progesterone, a naturally occurring hormone. A meta-analysis from 1996 found that people taking combined contraceptives have a slightly increased risk for breast cancer within 10 years of usage. In recent years, progestin-only methods of contraception — including pills, injectables, implants, and intrauterine devices (IUDs) — have become more popular. In England, drug prescriptions increased from 1.9 million in 2010 to 3.3 million in 2020. Until now, however, there has been limited research on the impact of progestin-only contraceptives on breast cancer risk. Recently, researchers investigated the link between hormonal contraceptive use and break cancer risk. Like combined pills, they found that progestin-only contraceptives slightly increase breast cancer risk. The study was published in PLOS Medicine.
Breast cancer and hormonal contraceptives For the study, the researchers analyzed health records from a UK primary care database. They included data from 9,498 women aged under 50 years old with breast cancer and 18,171 women without. Altogether, 44% of women with breast cancer and 39% of those without had a prescription for hormonal contraceptives. About half of these were for progestin-only preparations. Ultimately, the researchers found that combined contraceptive pill use increased breast cancer risk by 23%. They also found that oral progestin-only contraceptive pills increased breast cancer risk by 29%. Was this helpful? Other progestin-only formulations, including injectables, implants, and intrauterine devices (IUDs), increased breast cancer risk by 18%, 28%, and 21%, respectively. The researchers added that five years of oral contraceptive use was linked to breast cancer incidence in 8 per 100,000 users aged 16 to 20 years old and an incidence of 265 per 100,000 users aged 35- 39 years old.
Increased cancer risk is relatively small Dr. Irene M. Kang, medical director of women’s health medical oncology at City of Hope Orange County, not involved in the study, told Medical News Today: “All medications have risks and benefits, which is why discussing concerns with your provider is essential. Negative effects of oral contraceptives include strokes, heart attacks and blood clots. Research has shown that oral contraceptives can impact an individual’s risk of certain types of cancer – in some cases upwards, and in some cases, such as ovarian and endometrial cancers, downwards – through changing the levels of estrogen and progesterone. Additional benefits are family planning and more regulated menstrual cycles.” Dr. Lilian Harris, a medical oncologist at Novant Health Cancer Institute, not involved in the study, agreed that hormonal contraceptives have risks and benefits: “For example, they can protect against pelvic inflammatory disease and help with menstrual pain, […] fibroids, endometriosis and acne. They have also been shown to decrease the risk of […] uterine cancers. Conversely, there are also potential risks with any medication. For oral contraceptives, these risks can range from nausea, headaches, and breast tenderness to […] increased risk for breast cancer.” The researchers concluded that current or recent progestin-only contraceptives are linked to a slight increase in breast cancer risk. They say that such risks must be balanced against the benefits of contraceptives in childbearing years. Was this helpful?
Study limitations  When asked about the study’s limitations, Dr. Kang noted that due to the study design, it only explains short-term risk associations as opposed to long-term risk. Dr. Kristina Shaffer, breast surgical oncologist at Novant Health Cancer Institute, not involved in the study, also told MNT: “In addition, the study included premenopausal women, an age group where breast cancer incidence is lower, meaning that other factors may have been driving the slightly higher risk demonstrated in the study. For example, while the study did account for some of the factors known to be related to breast cancer risk, it did not account for family history, genetic predisposition, or history of atypical breast cells which are well-established to impact breast cancer risk.” Implications for contraceptives use MNT also spoke with Dr. Parvin Peddi, board certified medical oncologist and director of Breast Medical Oncology for the Margie Petersen Breast Center at Providence Saint John’s Health Center and Associate Professor of Medical Oncology at Saint John’s Cancer Institute in Santa Monica, CA, not involved in the study.

“[The] main take home message is that this study finds that women do not need to choose a progesterone only containing birth control medication because of perceived lower risk of birth cancer.”

– Dr. Peddie

“On the other hand, it’s important to note that the absolute increased risk of breast cancer from any of these medications is quite low and this study should not dissuade women from using hormone-containing birth controls,” Dr. Peddie explained. “Risk of breast cancer was seen in less than 0.5% of women age 35-39 years old due to use of these medications and in even fewer women who used these medications at a younger age.” Dr. Schaffer agreed that while the increase in risk may sound high at 20-30%, it is relatively small. “For instance, if the risk of a 30-year-old female developing breast cancer is 5%, then a relative increase of 20% would bring her risk to 6%. And this is why the study concludes that there is a slight increase in breast cancer risk,” she explained. Dr. Kang also noted: “As with all cancers, your breast cancer risk increases with age, and in this case, also with the length of time that hormonal contraceptives are used. If you are at a higher risk for breast cancer, switching to a hormone-free birth control may be a more beneficial option for you. If you are diagnosed with breast cancer, seek care from an expert who specializes in your type of cancer.” “Finding breast cancer early is one of the most important factors in successful treatment of this disease — and that’s why self-exams and screenings are so vital,” Dr. Kang concluded.

中国年轻乳腺癌诊疗专家共识（2022） 中国临床肿瘤学会乳腺癌专家委员会 中国抗癌协会乳腺癌专业委员会 中华医学会外科学分会乳腺外科学组 （二）避孕药物和孕激素节育器 一项基于亚洲人群的研究显示，人工流产是乳腺癌的独立危险因素［123］。因此，建议所有性生活活跃的年轻乳腺癌患者应采取适当的避孕措施。没有生育需求的患者可以考虑男性或女性绝育。 多项研究表明激素类避孕方式与乳腺癌发病或复发风险升高有关。我国一项系统分析提示，口服避孕药可能会增加中国女性乳腺癌的发病风险（随机效应模型比值比1.46）［124］。另有来自欧美的研究显示，外源性激素使用是乳腺导管原位癌患者术后复发的高危因素之一（5年局部复发率8.7%与 5.2%），在诊断乳腺癌后继续使用孕激素节育环将增加乳腺癌的复发风险（未校正风险比3.39）［125, 126］。对于尚未患有乳腺癌的BRCA1突变基因携带者，建议避免在年轻时服用激素类避孕药。加拿大一项纳入2 492例BRCA1突变携带者的病例对照研究表明，在25岁之前服用过口服避孕药者（即使只有1次），其在40岁之前发生乳腺癌的风险显著增加（比值比1.19~1.45）［127］。 孕激素节育器除了避孕外，还经常被用来治疗子宫内膜增厚，包括可能会用于他莫昔芬引起的子宫内膜增厚。但既往在HR阳性和HR阴性患者中开展的研究表明，孕激素节育器可能会增加乳腺癌患者的复发风险［125］。尽管相关研究结论不完全一致［128, 129］，对乳腺癌患者使用孕激素节育器（如曼月乐环）处理子宫内膜病变还是应持谨慎态度。 与会专家针对乳腺癌患者是否可以放置含孕激素的宫内节育器如曼月乐环、是否可以长期服用口服避孕药均未能达成共识。为了尽量减少乳腺癌复发，无论HR状态如何，建议年轻乳腺癌患者首选屏障避孕法或不含激素的宫内节育器，尽量避免长期使用激素类避孕方法。此外，紧急避孕药对于任何女性而言都不适合作为常规避孕方式，乳腺癌患者同样应做好其他高效避孕措施。

避孕套IUD环，属于多见避孕措施吧。长期吃药肯定会有问题。个人体质不同，有些人过敏或者无效之类的，可选方式就少了。天然妊娠保护卵巢，哺乳保护乳房，现代社会很多女人选择不生或者少生，不哺乳，或者人工受孕，再外加激素干扰，副作用显而易见。

Cervical cancer: Women who have used oral contraceptives for 5 or more years have a higher risk of cervical cancer than women who have never used oral contraceptives. The longer a woman uses oral contraceptives, the greater the increase in her risk of cervical cancer. One study found a 10% increased risk for less than 5 years of use, a 60% increased risk with 5–9 years of use, and a doubling of the risk with 10 or more years of use (9). https://www.cancer.gov/about-cancer/causes-prevention/risk/hormones/oral-contraceptives-fact-sheet#:~:text=The%20longer%20a%20woman%20uses,years%20of%20use%20(9). In the CPRD data, there was a significant increase in risk of breast cancer associated with hormonal contraceptive use, regardless of whether the contraceptive last prescribed was a combined (oestrogen and progestogen) oral preparation (23%), a progestogen-only oral preparation (26%), an injected progestogen (25%), or a progestogen-releasing intra-uterine device (32%);  https://www.ceu.ox.ac.uk/news/any-type-of-hormonal-contraceptive-may-increase-risk-of-breast-cancer

我医生说吃避孕药可以防止更年期的骨质疏松，能吃吗？

最近几年的研究是slightly增加乳腺癌几率的，我因为有乳腺增生比较谨慎，在决定要不要用避孕药的时候做过一些research。然后见ob的时候问了一下，她也证实了。我记得增加的几率也不大就是了。

吃避孕药不一定是为了避孕，比如子宫内膜异位，能用避孕药控制已经是幸运。

避孕药的说明上是写着的，有说法说会增加乳腺癌风险，但没有确实数据支持。然后也说服用避孕药可能减低卵巢癌和子宫内膜癌风险。主要看哪个风险更大吧。相对来说，卵巢癌和子宫内膜癌更凶险。

根据我妈妈主治医生分析，我妈妈乳瘤的成因：
1）只生了一个娃，乳汁未能充分释放，所以导致乳腺导管瘤。
2）长期口服避孕药。
所以古时候乳瘤发病率应该低很多。

所以彭祖活800岁也没啥稀奇的？

不婚不育本来就会增加各种妇科癌症的概率，人的各种器官都是有用的，你不用当然不好

那为啥养宠物都是绝育的寿命更长呢？

这是神话吧？ 有没有彭祖都不一定呢

古时候任何肿瘤发病率都低

寿命都到不了得癌症

lianqiao 发表于 2023-11-26 14:10

有这说法？

啥意思，避孕药增加乳腺癌几率不是很well published fact吗？
qgp 发表于 2023-11-26 08:11

我也以为呢，改变激素的，想想也不会完全无害

太频繁生育也不好啊，以前生10个8个孩子的年代，很多孩子都活不到成年，妈妈身体也不好

因为古人很多40人就没了，现代人活得长

有去德州治疗乳腺癌的人说那里的医生说很多病人都是用长期避孕药的，但避孕药厂砸了大钱游说，医生们也只是自己的临床观察私下跟病人说说

版上讨论是停药后会得病。应该还是激素问题吧。这药一吃就不能停的感觉。

有。绝育的狗要长寿。

不做什么事都没了，沾上男的就事多，女的完全可以自己解决

但是宠物绝育了就是完全没有任何荷尔蒙分泌了。人类不可能愿意放弃这些吧。我感觉就是这些荷尔蒙起伏如果不能完全消除，那么不得到释放反而更不好。

生孩子时候荷尔蒙起伏更大。见过好几个生娃后一两年乳腺癌的

去跟前面那个古人都活200岁的说

我前一段时间因为例假一直不停，吃了几个月的避孕药，吃上以后马上感觉胸部肿胀酸痛，后来停了以后就没有了。不知道是不是我太敏感。

除了乳腺癌还有啥

应该是有影响的。看网上说胸部如果有结节要慎吃避孕药。 不过我不知道胸部结节和乳腺癌的区别是什么，看网上说没啥关联？

避孕药治青春痘有奇效。我用任何中西药、护肤品、调整作息饮食都治不了青春痘，吃避孕药马上见效。

请问甲减吃每天吃的药 会不会致癌？

我听说的是避孕药停药五年时 得乳腺癌的比率大

我上个世纪80年代就高中毕业了。
xiaxie8 发表于 2023-11-26 12:29

No wonder. 已经老糊涂啦

好像是最近的reaearch，我吃完夜宵一会儿贴上来 之前看breast cancer risk factor我以为是饮食、作息、基因、抽烟喝酒，所以也不知道是我对science理解不好，还是说社会不想让女性知道hormone based 避孕药的危害
wielkacytryna 发表于 2023-11-26 01:06

荷尔蒙based的避孕药是会增加乳腺癌几率的。 药盒上写的都是。 但是你去问医生，医生会告诉你那是小概率事件。 这后面谁给了钱lobby, 谁拿了钱回扣。谁知道。

至今不知道避孕药长啥样。。。

大好年华（15-45岁）的健康女性服用药物干扰自然的激素分泌，我觉得想想就是不自然的事情

但凡长期吃某种药，都有产生副作用的可能。特别是激素类，人体本身太精密了，外界的调节真不好说。

是的。我自己和有认识的人都是这样。小概率事件 发生在自己身上就是灾难
