Tumors that Pose No Harm: Learn About Their Kinds, Possibility of Cancer, and Further Insights
In our bodies, tumors are abnormal growths that develop when cells reproduce in an uncontrolled way [7]. While some tumors are harmless, others can pose a threat to our health. Let's delve into the world of benign tumors and understand their potential risks and the diagnostic process.
Benign tumors, as the name suggests, are not cancerous and do not invade other parts of the body [6]. However, certain benign tumors can transform into malignant ones over time due to factors such as genetic mutations, chronic inflammation, and prolonged exposure to carcinogens [1][5].
For instance, Colonic adenomatous polyps may develop into colorectal cancer if left untreated [1]. Atypical moles (dysplastic nevi) potentially evolve into melanoma, a type of skin cancer [1]. Leiomyomas (uterine fibroids) can possibly transform into leiomyosarcomas [1]. Papillomas caused by HPV are linked to increased risk of cervical, throat, or bladder cancer [1]. Even pulmonary hamartomas, usually benign lung tumors, have been reported to undergo malignant transformation in rare cases [3].
While most benign tumors remain non-cancerous, their progression to malignancy depends on multiple factors and is relatively uncommon but clinically significant [2][4][5].
One common type of benign tumor is Lipomas, which are the most common soft tissue tumors in adults and consist of fatty tissue [2]. Lipomas most often affect people aged 40-60 years and commonly form on the arms, shoulders, upper back, buttocks, and upper thighs [2]. Fortunately, Lipomas very rarely become cancerous or cause any other complications [2].
Another type of benign tumor is Hemangiomas, a common type of birthmark in children that occur due to blood vessels growing at an abnormal rate [4]. Hemangiomas are very rarely cancerous [4]. They usually develop on the surface of the skin or just below, but some types can occur throughout the body [4].
Fibroids, which are benign tumors that affect females of childbearing age and grow in the wall of the uterus, are almost always noncancerous [3]. However, they can cause pain and abnormal bleeding, and they can result in difficulty getting pregnant or maintaining pregnancy [3]. In rare cases, fibromas turn into fibrosarcomas, which are cancerous [2].
Diagnosing a benign tumor can involve imaging tests such as CT scans, MRI scans, mammograms, ultrasound scans, and X-rays [6]. Biopsies of the tumor may help doctors rule out cancer and determine the most appropriate course of treatment [6]. It's important to note that a biopsy may miss areas where there are more cancer cells [6]. Therefore, it can be hard to predict how certain tumors will behave in the future, so doctors may keep monitoring them over time [6].
If a person notices they have an unusual lump on their body, they should consult a doctor immediately [6]. Early detection and monitoring can significantly improve the chances of managing benign tumors effectively and minimizing any potential risks.
- Although fibroids are usually non-cancerous, in rare cases, they can transform into fibrosarcomas, which are cancerous.
- Atypical moles can potentially evolve into melanoma, a type of skin cancer.
- Colonic adenomatous polyps may develop into colorectal cancer if left untreated, making it crucial to be aware of various health-and-wellness issues and regular medical-condition checks.
- Science has discovered that certain benign tumors can transform into malignant ones over time due to factors like genetic mutations, chronic inflammation, and prolonged exposure to carcinogens.
- While lipomas are the most common soft tissue tumors in adults, consisting of fatty tissue, fortunately, they very rarely become cancerous or cause any other complications.
