Sternum issues
Doctor, I have a question.
I suddenly noticed a bruise on the front of my right calf, and I don't recall hitting it.
It doesn't hurt much (today it has faded significantly and is almost healed).
Additionally, a few days ago, I had some redness and swelling in the gums above one of my teeth, but that has since resolved.
On November 10, I had a blood test, and the report showed a white blood cell count of 4500/µL (with other white blood cell classifications normal) (the standard range is 4000-11000).
However, this time my white blood cell count is lower than before, as it used to be between 5000-6000.
My red blood cell count is 5.3 x 10^6, hemoglobin is 15.8 g/dL, and platelets are 259 x 10^3/µL, all of which are normal.
I am concerned about the possibility of leukemia, so for the past two days, I have been pressing on my sternum with my fingers.
Initially, it didn't hurt much, but this morning I woke up feeling a slight tenderness at the junction of my sternum and ribs, similar to the pain of a bruise.
Is there still a possibility of leukemia? Is it abnormal for my white blood cell count to be slightly lower than before? I am a bit worried.

1.
Is there still a possibility of blood cancer?
A: No, blood cancer refers to leukemia, which is characterized by the abnormal proliferation of white blood cells rather than a decrease.
2.
Is it abnormal that the white blood cell count is slightly lower than before?
A: As long as it is within the normal range, fluctuations can occur depending on the individual's health status.
What constitutes as abnormal? Wishing you good health.

When it comes to concerns about blood cancer, particularly in the context of symptoms like unexplained bruising, bone pain, and changes in blood cell counts, it is essential to approach the situation with a clear understanding of the underlying medical principles.
Firstly, the appearance of a bruise without any recollection of trauma can be concerning, especially when combined with other symptoms such as localized pain or swelling. In your case, the bruise on your right shin that appeared suddenly and the mild tenderness in your sternum could be indicative of various conditions, but they do not necessarily point directly to blood cancer.
Aplastic anemia, for instance, is a condition where the bone marrow fails to produce adequate amounts of blood cells, leading to symptoms like fatigue, increased susceptibility to infections, and easy bruising. However, your blood test results show that your white blood cell count is within the normal range, albeit slightly lower than your previous counts. Normal ranges for white blood cells are typically between 4,000 and 11,000 cells per microliter, and your count of 4,500 cells per microliter is still considered normal. It is important to note that variations in blood counts can occur due to numerous benign factors, including stress, hydration status, and even time of day.
The tenderness you are experiencing in the sternum area, especially if it is localized and not accompanied by other systemic symptoms (like fever, weight loss, or significant fatigue), may not be directly related to a hematological malignancy. Bone pain associated with blood cancers, such as leukemia or lymphoma, often presents as persistent, deep, and sometimes debilitating pain, rather than localized tenderness that is transient.
Moreover, the presence of gingival swelling or redness can be attributed to dental issues or localized infections rather than a hematological disorder. While it is true that certain blood cancers can lead to gum problems due to thrombocytopenia (low platelet count), your platelet count appears normal at 259,000 cells per microliter.
In summary, while your concerns about blood cancer are valid, the evidence from your blood tests and the nature of your symptoms suggest that the likelihood of a serious hematological condition is low. However, it is crucial to continue monitoring your symptoms and maintain open communication with your healthcare provider. If the tenderness in your sternum persists or worsens, or if you develop new symptoms, further evaluation may be warranted.
For peace of mind, consider discussing your concerns with a hematologist or an oncologist, who can provide specialized insights and possibly recommend further testing if deemed necessary. Regular follow-ups and blood tests can help track any changes in your health status, ensuring that any potential issues are caught early. Remember, being proactive about your health is key, and seeking professional advice is always a prudent step when in doubt.
