Unexplained Growths: A Guide for Teens and Parents - Family Medicine

The body develops foreign objects?


Hello, I have a protrusion at the base of my spine that appeared when I was in the second grade, and I am now in the ninth grade.
It hasn't changed in size, hasn't caused any pain, and I have seen a family doctor who took an X-ray.
The doctor said it is just normal tissue.
However, I don't understand why this tissue grew there without any reason.
Could you please help me understand? Thank you.

Hello, the protrusion of the coccyx is actually similar to a monkey's tail.
However, as humans evolved as higher organisms, the tail disappeared in the process.
Nonetheless, humans still share primate genes, which is why a small number of people exhibit this phenomenon.
Only a very few individuals have a more pronounced protrusion.
Since it does not cause pain and will not continue to grow, I suggest you not to worry about it.
Dr.

Understanding unexplained growths, especially in adolescents, can be a source of concern for both teens and their parents. It’s important to approach this topic with a clear understanding of the body’s growth processes and what might cause unusual growths.

In your case, the bump you mentioned at the base of your spine, which appeared when you were in the second grade and has not changed in size or caused any pain, is likely benign. The fact that a physician has already evaluated it and determined that it is "just normal tissue" is reassuring. Many growths can occur during childhood and adolescence due to a variety of reasons, including genetic factors, hormonal changes, and normal variations in body development.


Common Causes of Growths
1. Lipomas: These are benign tumors made of fat tissue that can occur anywhere in the body, including the back. They are usually soft, movable, and painless.

2. Sebaceous Cysts: These are small lumps beneath the skin that can occur when hair follicles become clogged. They are also generally harmless unless they become infected.

3. Bone Growths: Sometimes, growths can be related to the underlying bone structure, such as osteochondromas, which are benign bone tumors that can develop during periods of rapid growth.

4. Normal Variations: As children grow, their bodies can develop in unique ways. Some growths may simply be normal anatomical variations that do not require treatment.


When to Seek Further Evaluation
While your current situation seems stable, it’s important to monitor any changes. If the bump starts to grow, changes in color, becomes painful, or if you experience any other symptoms, it would be wise to consult a healthcare provider again. They might recommend further imaging studies or a referral to a specialist, such as an orthopedic surgeon or a dermatologist, for a more detailed evaluation.


Understanding Growth Patterns
During adolescence, the body undergoes significant changes due to hormonal influences, particularly during puberty. Growth spurts can lead to various physical changes, and it’s not uncommon for adolescents to notice new growths or changes in their bodies.

Parental Guidance
For parents, it’s crucial to maintain open communication with your child about their body changes. Encourage them to express any concerns they may have about their growth or any physical changes. Regular check-ups with a pediatrician can help ensure that any growths are monitored appropriately.


Conclusion
In summary, the bump you have described is likely benign, especially since it has not changed or caused discomfort. It’s always best to follow up with a healthcare provider if there are any changes or new symptoms. Understanding that growths can be a normal part of development can help alleviate concerns. Regular check-ups and open communication about health can foster a supportive environment for both teens and their parents as they navigate the complexities of growth and development.
