Skin Lumps: When Parents Should Worry
Noticing a skin lump on a child can be scary. Fortunately, most skin lumps are not a major cause for concern.
Noticing a skin lump on a child can be scary for parents, and its easy to automatically assume the worst. Fortunately, most skin lumps are benign and not a major cause for concern, according to Dr. Saeed Awan, a pediatric general and thoracic surgeon at CHOC.
Some children are born with skin lumps, and some lumps appear later. The majority of patients with skin lumps will not have any other symptoms, but they can include pain, bleeding, redness, loss of appetite and night sweats. Surgery is often recommended in order to remove these skin lumps, to avoid the risk of infection.

Lymph nodes are the most common lumps that parent notice and worry about. Most parents find lymph nodes in the neck area but can also notice them around the ears and at the back of the skull.
A pea-sized, rubbery node beneath the skin is nothing to worry about, says Dr. Awan. Healthy lymph nodes fluctuate in size- they grow and they shrink, but bad lymph nodes keep growing and are not subtle.
A lymph node over one centimeter in diameter needs further investigation by a medical professional, especially when associated with loss of weight or appetite, fever or night sweats.

Should I Be Concerned About A Lump Under The Skin After The Covid
Side effects of COVID-19 vaccines can include enlarged lymph nodes in the armpit or neck on the side where the person got vaccinated, which is very much a normal response to the vaccine and should go away within a week or two. If lump swelling persists beyond two weeks, talking to a medical professional is likely advised, says Harold Burstein, MD, PhD, a physician in the Breast Oncology program at Dana-Farber/Brigham and Womens Cancer Center.
The vaccine should not cause any swelling in the breast itself if you notice changes in the breast, let your doctor know.
Burstein also notes that Dana-Farber is advising breast cancer patients to get vaccinated in the arm on the opposite side of the breast in which they developed cancer to reduce any chance of lymphedema in breast cancer survivors.
Remember: Dana-Farber recommends that both cancer survivors, and active patients on therapy, should receive the COVID-19 when it is made available to them.

Most Common Bumps And Lumps On Puppies

Thankfully, cancer in puppies is rare. The most common types of lumps or bumps found on puppies are warts, skin tags, button tumors, and abscesses. In these cases, your vet may recommend a wart ointment or other skin treatment. There are also some products that claim to help dissolve normal fatty skin lumps on dogs. Its also not unusual for puppies to develop swelling at their vaccination injection site, caused by a conglomeration of immune cells that gather there.
Typically, this swelling subsides within a week. However, in rare cases, this gathering of cells can turn into a malignant tumor. Contact your vet if a vaccination lump lasts more than a week. They may advise you to keep a watchful eye on it and bring your pup in for a biopsy if the lump continues past three months, is more than an inch in diameter, or continues to grow or change shape.
Although its rare, it is possible for puppies to develop certain types of cancer, so its important to have any lumps, bumps, or other changes in your puppys skin examined by a veterinarian.
