This short post is a summary of a full blog post you can read on my new Substack blog: The VajendaThis is the 2nd of 3 short summaries I will send out while followers of this space sign up for the new blog. After that, I will stop posting blogs on this site, although other information about my books and appearances will continue to be updated here on

I look forward to seeing you all at The Vajenda!


We’ve discussed a potential link between the COVID-19 vaccine and irregular periods, but did you know the vaccine can also affect your mammogram?

As a vaccination triggers the immune system, it can cause lymph nodes to swell, typically those closest to the vaccination site (armpit and neck, most commonly). This is totally normal. It means the lymph nodes have received the signal that something foreign has been injected, and they are now doing their thing. This is not a COVID-19 vaccine phenomenon, it is a vaccine phenomenon.

These swollen lymph nodes can show up on a mammogram which then need to be investigated to make sure they are benign (not cancer). That means an ultrasound or two and that also adds expense.
