It is known that a Canadian woman suffered an extremely large chest size side effect after receiving the COVID-19 vaccine.

According to the British media Daily Mail, a 19-year-old woman living in Canada's chest grew from a B-cup size to a triple G-cup six months after receiving two COVID-19 vaccine shots.

Her chest began to tingle and grew slightly after receiving her first dose of the Pfizer COVID vaccine in September 2022, and her symptoms worsened after receiving her second dose about three weeks later.




Six months after inoculation, her chest grew so much that she went to the hospital.

With no underlying disease, she appeared to have swollen and saggy chest, but no mass.

The medical team estimated that the COVID-19 vaccine may have caused pseudoangiomatous stromal proliferation (PASH).




PASH generally refers to the overgrowth of cells that cause a benign mass in the breast.

It is a benign breast disease found in fewer than 200 people worldwide since it was first reported in 1986.

However, there are only 20 known cases of PASH that cause extreme breast growth, which is a rare case.




Medical staff are the first to show a link between PASH and the vaccine, but they cannot prove that PASH is a clear cause.

While it is unclear how the vaccine grew the breast, some case studies have suggested that the COVID vaccine may cause an immune response, causing the lymph nodes to temporarily swell and make the breast appear larger.

Researchers at the University of Pennsylvania previously discovered in 2021 that the COVID vaccine could cause lymph node swelling, leading to abnormal findings in mammography and mammography.

Researchers said at the time "This is a normal response to the COVID vaccine and there is no need to worry." he said.

However, he said additional research is needed.

The woman underwent breast reduction surgery 11 months after her first COVID vaccination, and doctors removed about 3.6 kg of tissue during the operation. This reduced the size of the chest to a double D cup. Since then, the chest has not grown any more, but it is asymmetric, so the woman is considering further surgery. The case was published in the journal 『Plastic and Reconstructive Surgery』.
