Alejandro: How can keloid became a threat?
Doctor: That is a thing that I most always be aware of because I'm a surgeon , keloid means discarding tissue usually when you have a wound healing, the mehcanism is one of the parts attached to the other part and that's it and usually it is a line lefting where the wound was, that's the scar, that is a common scar, but when you have keloid that scar overgrowns. You have your normal scar tissue or you can have keloid which is an unorganized growth of the scar, it can become a threat because sometimes it can grow too much that it can compromise a tissue or an organ, for example if you have a scar in your hand and you have keloid the scar can grow as much as it can like, cause compression of your blood flow and it could change because it under more pressure . And it can became a threat for example if you have scar on your face and you have keloid it can deform your face because of the overgrowth of the scar, that's a keloid. You can have three types of scar, the reger scar you can have the hypertrophic scar which is in the same line where you have the scar but it grows on the top and you can have keloid where it grows on the other tissues around the scar that's a keloid
Alejandro: What are the causes of Seborrheic Keratosis?
Doctor: Is a disease of the hair follicles, people with a lot of hair they can have this problem and it is mainly caused because you can have a lot of cevoreic glands that produce the material necessary to keep moisten the surface of the skin. When you have this problem that is because the pores of the skin become obstructed and then you have another growth of the gland below the skin and you can have an inflammatory process you can have a swelling of the skull for example or in the area where you have a lot of hair , swelling and blisters and you can have a lot of pain, redness things like that is Seborrheic Keratosis. The causes of it , I think it also have to be with the inmune system and it usually attacks people with inmune problems .
Alejandro: So, because of the sweating of the glands, and because the pores obstructed it cannot get out of the body and it causes inflammation?
Doctor: Yeah, you’re right. That’s exactly the process.
Alejandro: What causes blisters?
Doctor: Blisters is one of the way the skin reacts when you have an injury. It’s when you get an injury and your immune system activates. A lot of cells go to where the injury lies and one kind of cell starts eating all the damaged cells. When you hit yourself, the phagocytes start to take away or eat all the dead cells. In case an injury happens, our immune system starts taking away all dead cells and making new cells. When we see this through a microscope, all we see is like water, liquid. You can have blisters also in an infection, because all those dead cells have been taken away by the phagocytes.
Alejandro: How can skin cancer be diagnosed?
Doctor: Well, when a person has skin cancer it usually appears in the areas that are exposed on the son, is more common in light-skinned people than in dark-skinned people. The way this is diagnosed is through a vaccine. You have to take blood samples and present it in a laboratory. There the pathologists will tell you everything you need to know. But usually it all starts looking like you have scars in the skin. What they do in the laboratory is to check and compare your cells with some regular cells to see if they have something weird going on. Cancer cells look really ugly while regular look pretty. Cancer cells have irregular borders, big parts, all messed up and ill.
Alejandro: Well you sort of answered the next question but we want to know, what exactly is a cancer cell?
Doctor: A cancer cell has something to do with mitosis. Every cell has the ability to divide from one cell to another one by reproducing alone. They reproduce exponentially. This is how our cells are reproduced. Every day this process of division of cell, we might have a problem during the division of a cell. For example, during the division of chromosomes, the amount of chromosomes could go dividing completely wrong and one cell can have more than the other one. Usually our immune system has the ability to recognize this cells and destroying them. This cells sometimes become cancerous cells. But sometimes during this process you can have this slight difference. So the immune system doesn’t recognize this cells and they start growing or dividing. They’ll start reproducing similar to the regular cells, so you have a group of cells different from the original cells, that’s what a cancerous cell is.
