Title: Unusual Breast Enlargement After COVID-19 Vaccination: A Rare Case Study
A 19-year-old girl has made medical history by becoming the first person to possibly link breast enlargement with the COVID-19 vaccine. After receiving the Pfizer vaccine, her bra size increased dramatically from a B cup to a triple G cup in just six months.
The Toronto-based study, published in the Plastic & Reconstructive Surgery-Global Open journal, describes her unusual case. The girl began experiencing breast enlargement symptoms about a week after her first vaccine dose, with symptoms worsening after the second dose.
Dubbed the "Pfizer boob job" phenomenon, reports of breast enhancement following vaccination have emerged, but no causal evidence exists. While lymph node swelling is a known side effect of COVID-19 vaccines, changes in breast tissue structure or density are extremely rare.
The teenager was later diagnosed with an extremely rare condition called pseudo-angiomatous stromal hyperplasia (PASH)-related gigantomastia, with fewer than 20 recorded cases globally. Typically caused by benign tumors, the girl did not have any breast lumps. This is believed to be the first case associating PASH with a vaccine.
Initially, doctors treated her with corticosteroids and antibiotics, but to no avail. Her breasts stopped growing after six months but left her with difficulties in daily life. In 2023, she underwent a breast reduction surgery, but due to heavy bleeding, surgeons could only remove part of the breast tissue. Post-operative, her breasts were reduced to a double D cup, and she is considering further surgery to restore her original size.
However, healthcare professionals emphasize that there’s no direct evidence linking COVID-19 vaccines to this rare breast condition. While vaccine-associated lymph node swelling has been widely documented, changes in breast tissue structure or density are exceptionally rare. Further research is needed to explore potential connections between vaccines, PASH, and rapid breast growth.
Since 2020, over 136 billion doses of COVID-19 vaccines have been administered globally, highlighting their overall benefit despite occasional adverse reactions.
