I’ve been using deodorant regularly for years, but recently a friend of mine said it can cause breast cancer and now I’m super paranoid about it. T.T What if mine is aluminium-free, does that make a difference?

Yes, it is indeed possible for two pairs of identical twins to be born from two fertilized eggs, although this scenario is quite rare. To clarify the terminology:
- Identical Twins (Monozygotic Twins): These twins arise from a single fertilized egg (zygote) that splits into two embryos. They share 100% of their genetic material and are genetically identical.
- Fraternal Twins (Dizygotic Twins): These twins occur when two separate eggs are fertilized by two different sperm cells. They share about 50% of their genetic material, similar to regular siblings, and can be of the same sex or different sexes.
Now, the scenario you described involves two separate fertilized eggs, each of which splits to form identical twins. This can happen as follows:
- Two Fertilized Eggs: In this case, two separate eggs are released during ovulation and each is fertilized by a different sperm cell. This results in two zygotes.
- Splitting of Each Zygote: If each of these zygotes (fertilized eggs) undergoes a division process (which is rare), each can split into two embryos. This would lead to the formation of two pairs of identical twins.
Thus, the outcome would be four babies in total: two from the first zygote and two from the second zygote, with each pair being genetically identical.
Mechanisms and Considerations
- Occurrence: The occurrence of two fertilized eggs both splitting is extremely rare and is not well-documented in the literature. The likelihood of this happening is much lower than the occurrence of either identical or fraternal twins alone.
- Genetic Implications: In this scenario, the two pairs of identical twins would share 100% of their genetic material within each pair but only about 50% of their genetic material with the other pair, as they originated from different zygotes.
- Clinical Considerations: From a clinical perspective, managing a pregnancy with multiple sets of twins (especially identical twins) can be complex. The risks associated with twin pregnancies, such as preterm birth, growth restriction, and complications related to shared placental circulation (in the case of identical twins), would need to be carefully monitored.
- Ultrasound Monitoring: Early ultrasound examinations can help determine the number of embryos and their chorionicity and amnionicity, which are crucial for assessing risks and planning for delivery.
Conclusion
While the phenomenon of two pairs of identical twins resulting from two fertilized eggs is theoretically possible, it is exceedingly rare. The implications for prenatal care and delivery would require careful consideration and monitoring to ensure the health and safety of both the mother and the babies.

Hi there! As a breast cancer oncologist, I want to reassure you about a common concern: the idea that deodorants cause breast cancer. This is a myth that many people worry about, but the good news is that there’s no scientific evidence to back it up.
Some people have raised concerns about ingredients like aluminum and parabens in deodorants, but extensive research has shown that these substances do not increase your risk of breast cancer.
However, there is one specific situation to be aware of – during radiotherapy for breast cancer, deodorants with aluminum are often discouraged, as they can interact with the radiation given. But this advice is only applicable to women with proven breast cancer undergoing radiotherapy.
I hope this helps ease your mind!
