The part of the skin that has an abnormal growth compared with the other parts of the skin around it is called a lesion. Lesions are of 2 types, primary and secondary. Primary lesions are the abnormal skin conditions that can be either occurring by birth or acquired over a lifetime. When the primary skin lesions are irritated or manipulated, it results in the secondary lesions. For instance, a mole when scratched hard can turn into a crust resulting in a secondary lesion.
- Acne that is located on the face, chest and upper back

- The rashes are in the pattern of linear stripes, and often found in the torso, and face
- These are found on the face, neck and torso
- The cysts that cause pain and pressure are large, and they grow very slowly
- These are not malignant and do not cause cancer
- This is a condition that needs emergency treatment. This is caused by staph bacteria, and these cannot be treated with antibiotics.
- When the bacteria enters into the scrape or cut, the infection is caused
- They are similar to the spider bite and are like red pimples. They are raised and cause pain
- Powerful antibiotics are required to treat this and can lead to blood infection
- This is another condition that should be treated as a medical emergency. They ooze faster and spread the infection. It leads to swollen skin that changes to colour red and becomes painful

- Human papillomavirus of various types can cause keloids. They are found on the skin and mucous membranes. They can occur in single or in groups.
- They are contagious and can be passed on to others
Infection on the skin is the major cause for the condition. Wart is a fine example. When wart affected person comes in contact with others, the infection is passed on. The same is the case with cold sores and genital herpes. Skin lesions can be spread all over the body in the case of chicken pox and shingles.
A few types of lesions can be genetic. One of the examples is freckles and birthmarks.
Allergic reactions can lead to lesions like eczema and psoriasis.
Diabetes and inadequate blood flow in the body can also lead to skin lesions in a few cases
In a few cases, it can be seen that the members having warts or other types of lesions like freckles are around in the extended family too. Hereditary is a factor that causes such types of lesions.
Autoimmune diseases can also trigger lesions in a few people. A few people can develop rashes that disappear in a few hours after eating certain types of foods
A complete physical examination is required to diagnose skin lesions. All symptoms are taken into account to find the root cause of the lesion.
Skin samples are taken for biopsy in a few cases. This is often done to check if the condition is cancerous. Moles and warts that keep changing in size and colour are checked for cancerous growth.
The core cause of the condition has to be analyzed to treat the lesion. The medical history and the type of lesion play a major role in identifying how to treat the condition.
The doctors never go for surgery on the very first visit. The affected area is treated, and inflammation is brought down. When the condition can be controlled with the medications, the doctor might not refer to a surgeon. Topical creams are prescribed for itching, and to alleviate pain.
Oral medications are required if skin lesions are the effects of chicken pox or shingles. Eczema, psoriasis and other such types of lesions need advanced treatment and the duration of medication can be longer, even a year. This is however based on the specific requirements of the individual and the scenario.
Moles at times might not find the oral medications and topical creams potent enough to control them. This is where surgical intervention is required. This is most often done when the moles are suspicious. This means they can grow in size, and the colour can be changed. This is a symptom of skin cancer.
Hemangioma is a condition that is a result of the blood vessels that are not formed right. These are birthmarks, and they can be removed with ease. Laser surgery is how these are removed.
Apart from medical treatment, these lesions can also be treated by home care. Oatmeal baths and lotions often can lead to bringing down the burning and itching sensation caused by the lesions.
Avoiding contact with infected people can control skin lesions in many cases. The best examples are shingles and chicken pox.
However, not much can be done in case of freckles and warts.
Brain lesions: When the tissue of the brain is damaged by a disease or injury, then the condition is called a brain lesion. This is a very complicated condition to understand. There are various types of brain lesions. They can be of all sizes, small to very huge. They can be innocuous and can be life-threatening.
The symptoms of the brain lesions can vary based on the location, size, and severity. The symptoms are:
- Neck pain
- Vision changes, or pain in the eye
- Memory loss
- Difficulty in moving
- Personality, behavioural and mood changes
Brain lesions can be caused due to various reasons.
- Injury: Any trauma caused to the brain or head can lead to damaged tissue in the brain
- Immune system: A weak immune system can lead to this condition
- Chemicals: Exposure to a few chemicals can lead to changes in the brain chemicals and lead to a brain lesion
- A brain aneurysm or bulge in the brain can lead to a brain lesion
- Cancerous and non-cancerous brain tumours too can cause the brain lesion
- Brain inflammation can lead to a brain lesion
- Multiple sclerosis
The symptoms decide the diagnostic methods for the brain lesions. CT scan and MRI imaging help in finding the most accurate location of the brain lesion. The blood tests and various other lab tests will also be recommended by the doctor. The signs of infections bring in need for the advanced test.
Relieving symptoms is often why the treatments are opted for. There are treatment options that can also offer a cure, and improve the quality of life. The doctors, however, start with the watchful waiting period. This means, they wait and see if the lesions are growing or seeing any difference over a certain period of time.
The hard to reach lesions could not remove with surgery in earlier days. But now, these days, the advanced techniques are used to make it easy for the surgical removal of the lesions even in the toughest location.
When the lesions are not cancerous, they can be treated with antibiotics and a range of other medications
For the lesions that are cancerous, chemotherapy and radiation therapy are used to remove them.
If the lesions are because of the immune system problems, the medications are prescribed to suppress the immune system.
Brain lesions cannot be predicted or prevented. Environmental toxins and avoiding exposure to chemicals can keep off brain lesions that are resulting due to these factors. A few preventive measures are given as guidelines by the healthcare department.
- Quit smoking. Smoking can play a major role in causing blood pressure and aggravating aneurysm. This is a crucial cause for brain lesions.
- Controlling high blood pressure blood pressure, diabetes, and cholesterol is a wise way to stay off from brain lesions and various other health complications.
- Always keep the head protected with the right gear when involved in activities like skiing, skateboarding, and while riding a bike.
Any lesion should be watched for the growth in size and colours if on the skin, and the symptoms should watch in case of brain lesion. This can help in identifying them earlier and getting treated faster.
