How often do skin cancers are seen?
Skin cancers are the most common cancer type in humans. Skin is an organ with a large surface that enables our interaction with the outside world. Changes in this large surface are inevitable. Most of these changes (moles, sunspots, benign tumors etc.) are benign. However, some of them can be malignant tumors. In recent years, there is an important increase in malignant tumors because of the ozone layer thinning. However, most of the skin tumors can be cured and are not a big problem to the health of the patient.
What are the reasons of skin cancer?
Being exposed to sun for a long time, genetic predisposition, pale complexion, exposed to some chemicals for a long time, moles (nevus), festering sores are the most popular reasons of skin cancer.
Should I protect my skin from the sun?
Sunbathing is an activity loved by everyone in summers. However, the damage of the sun beams to skin also big. Especially people with pale complexion should avoid from the sun. The most important reason of the skin tumors is the sun beams. Besides this, sun beams cause the skin age in a younger age. You should use protective sun cream before exposed to sun.
How can I differentiate a benign spot from a malignant tumor?
You cannot see the difference. Sometimes, even the specialists cannot see the difference and they take a skin sample to examine in the lab. The only thing you can do is to see a doctor if you have a spot that have changes or a sore with blood and scab that does not heal in 3-4 weeks.
Should I be careful about the spots that appeared recently?
Spots and pigmented creations on the body are not dangerous most of the time. Sometimes, spots because of age or sun can be seen. However, if you realize a change in the existing moles or newly appeared ones, you should go to a doctor. These changes are these: the mole gets bigger in the last few months; its borders become asymmetrical and its color changes.
If a suspicious spot is detected, what procedures are followed?
If a spot with the possibility of being a tumor is detected, the only way for diagnosis is the pathological examine. If the area where the spot is taken off is small enough to repair (generally it is), taking of the complete spot and sending it to the pathology for research is the best way. With this way, the pathologist who examines the tissue has the chance of making a better diagnosis and for most of the case the diagnosis and the treatment are applied at the same time. For bigger spots, only some tissue is taken off and sent to pathology. The treatment is applied according to the report coming from pathology.
People around me keep saying “Do not have surgical operation. If you have the surgery, it may get spread.”Is it true?
This comes from a misbelief and it is completely wrong. If it is a malignant tumor and is not touched, then it will become bigger. However, if you have the surgery, your chances of treatment become higher. Sometimes, some doctors who are not an expert in this field take off the skin tumors with the thought that they are not malignant and do not send the tissue to pathology. If this non-diagnosed tissue is not taken off with a proper amount, it repeats and scatters to the body. This is named as the idea you mentioned in your question by the people. This is a wrong idea.
If I have the surgery, may the tumor reappear?
Yes it may. This probability also depends on the type of the tumor, but there is a possibility of reappearance. Skin tumors are mostly seen in the people with lights complexions because of the effects of the sun. Because of this, patients whose skin tumors are taken off have the chance of having skin tumors at other sides of the body exposed to same conditions. Thus, patients who have surgeries for skin tumors have the possibility of growing skin tumors again and they should be careful about it.
