Covid-19: vaccine can lead to lymph node swelling and misleading mammogram results


  • English
  • Arabic

Mammogram results from one to six weeks after a Covid-19 vaccination could be inaccurate if doctors misread enlarged lymph nodes as cancer.

Coronavirus vaccines are known to trigger a strong immune response in the body, and this in turn can lead to inflamed lymph nodes in the armpit.

The swollen glands are usually a good sign that the body’s immune system has responded appropriately to the vaccine and created antibodies.

We fully encourage people to get vaccinated, and in case they experience the below symptoms they should not panic

But swollen lymph nodes can also be a symptom of breast cancer, so women who have scheduled a screening immediately after vaccination might find their results worrying.

Dr Taghreed Al Mahmeed, a consultant breast surgeon at Al Zahra Hospital Dubai, said women should not panic if their mammogram results indicated enlarged lymph nodes.

“I have seen many female patients coming in worried with pain and light swelling in the underarm post the Covid-19 vaccination.

"However, after taking a full history and carrying out the appropriate investigations, and proceeding with the follow-up in two to three months, the results were back to normal," she said.

Mammograms should be carefully scheduled

The phenomenon of potentially misleading mammogram results after Covid-19 vaccination was published in recent international publications, including the American Journal of Roentgenology and the Journal of the American College of Radiology.

As a result, the Centres for Disease Control and Prevention in the US issued new guidelines for choosing the right time to schedule screening.

A mammogram is an X-ray picture where two views are taken of each breast.

Although the process is very important and in many cases should not be delayed, if there is no known risk or concern of breast cancer, the US health institute recommends that patients postpone mammograms for six weeks after the second dose of the Covid-19 vaccine.

Alternatively, women can schedule the mammogram just before the date of the first shot.

If lymph nodes do show up as swollen on a mammogram, Dr Al Mahmeed said it was advisable to have an ultrasound two or three months later.

"We fully encourage people to get vaccinated, and in case they experience the [lymph node] symptoms they should not panic but rather visit a doctor to ensure everything is OK,” she said.

What is graphene?

Graphene is extracted from graphite and is made up of pure carbon.

It is 200 times more resistant than steel and five times lighter than aluminum.

It conducts electricity better than any other material at room temperature.

It is thought that graphene could boost the useful life of batteries by 10 per cent.

Graphene can also detect cancer cells in the early stages of the disease.

The material was first discovered when Andre Geim and Konstantin Novoselov were 'playing' with graphite at the University of Manchester in 2004.

Hili 2: Unesco World Heritage site

The site is part of the Hili archaeological park in Al Ain. Excavations there have proved the existence of the earliest known agricultural communities in modern-day UAE. Some date to the Bronze Age but Hili 2 is an Iron Age site. The Iron Age witnessed the development of the falaj, a network of channels that funnelled water from natural springs in the area. Wells allowed settlements to be established, but falaj meant they could grow and thrive. Unesco, the UN's cultural body, awarded Al Ain's sites - including Hili 2 - world heritage status in 2011. Now the most recent dig at the site has revealed even more about the skilled people that lived and worked there.

Quick pearls of wisdom

Focus on gratitude: And do so deeply, he says. “Think of one to three things a day that you’re grateful for. It needs to be specific, too, don’t just say ‘air.’ Really think about it. If you’re grateful for, say, what your parents have done for you, that will motivate you to do more for the world.”

Know how to fight: Shetty married his wife, Radhi, three years ago (he met her in a meditation class before he went off and became a monk). He says they’ve had to learn to respect each other’s “fighting styles” – he’s a talk it-out-immediately person, while she needs space to think. “When you’re having an argument, remember, it’s not you against each other. It’s both of you against the problem. When you win, they lose. If you’re on a team you have to win together.”

UK's plans to cut net migration

Under the UK government’s proposals, migrants will have to spend 10 years in the UK before being able to apply for citizenship.

Skilled worker visas will require a university degree, and there will be tighter restrictions on recruitment for jobs with skills shortages.

But what are described as "high-contributing" individuals such as doctors and nurses could be fast-tracked through the system.

Language requirements will be increased for all immigration routes to ensure a higher level of English.

Rules will also be laid out for adult dependants, meaning they will have to demonstrate a basic understanding of the language.

The plans also call for stricter tests for colleges and universities offering places to foreign students and a reduction in the time graduates can remain in the UK after their studies from two years to 18 months.
