Q. What makes a tumour malignant or benign?
Doctor Answer is medically reviewed by SecondMedic medical review team.
A tumor is considered malignant or benign based on its characteristics and the context in which it exists. Malignant tumors are typically characterized by rapid growth, invasion into surrounding tissue, and a tendency to metastasize (spread throughout the body). Benign tumors, on the other hand, generally lack these features and remain localized to their area of origin.
The primary difference between malignant and benign tumors lies in how they behave. Unlike benign lesions, malignant ones can continue to grow locally in size due to unchecked cell division. They also tend to invade nearby tissues through direct physical contact as well as via local blood vessels and lymphatic systems (a process called “metastasis”). This means that unlike a benign tumor which is static - almost like a cyst - a malignant one will spread further unless treated appropriately; this ability to spread widely makes it particularly dangerous.
Malignancy is generally caused by an accumulation of genetic mutations resulting from DNA damage accumulated over time from both internal processes such as errors during cell division or external factors such as exposure to carcinogens or radiation. These mutations modify gene expression levels or increase the number of copies of existing genes thus promoting cancer development. As cells with mutated genes divide uncontrollably and form a mass (tumor), normal cells surrounding them die leaving an environment rich in nutrients that fuel further proliferation leading ultimately to disease progression if left untreated for long enough periods of time.

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
