Possible first signs of cancer

The symptoms caused by tumors is not always clear

Cancers, at least initially do not often clearly noticeable. Some symptoms may indicate a malignant tumor in the body.

When cancer is malignant cell growths. The Oncogenes That are responsible for cell formation and growth, more and more of the so-called Carcinogens affected, so that cell division and growth run incorrectly. Finally, more and more carcinogenic oncogenes are replaced by cells, so that a tumor develops in the organs or the bones. Through the blood stream, there is a risk of the formation of ulcers in other subsidiary organs, since the carcinogens are transported by the blood throughout the body. This is called metastasis.

Possible risk factors for cancer

These include smoking, obesity, alcohol abuse, or even years of ongoing professional contact with carcinogenic substances (for example, the exposure of nuclear workers at nuclear power plants, chemical workers and the like). Apart from damaging environmental influences also play a role in genetic susceptibility. Often a particular type of cancer occurs more frequently familial.

Potential early signs of cancer

Depending on which organ is primarily affected, can be observed:

• Coughing up blood, hoarseness constant that can not be attributed to overuse of the voice, smoking or a cold, disease, increased susceptibility to lung inflammation and Bronchialinfekte
• Difficulty swallowing
• Blood in stool, tarry stool (blood is blackened by the admixed stomach acid)
• Vomiting blood
• Blood in urine
• constant, violent Headache, Often accompanied by dizziness, impaired vision and hearing disorders
• Moles that change suddenly in their size and / or secrete color, secretions, or bleeding
• unexplained weight loss
• severe abdominal pain, often associated with nausea, vomiting and diarrhea
• Tiredness, fatigue, which can not be attributed to increased physical stress and strain
• for venipuncture: increased leukocyte (normal range: 7000-9500 leukocytes), which can not be attributed to other inflammatory diseases such as rheumatoid
• Leakage of secretions from the nipples
• in men: Breast Growth
  
• in women: spotting between days, painful periods, vaginal bleeding after menopause
• any wound or any ulcer that is not fully healed within three weeks.

Some of the above symptoms may also indicate an acute illness (such as violent Bausch Merzen with nausea and vomiting as a sign of appendicitis), or any other disease. Therefore, a rapid medical investigation is the occurrence of one or more of the symptoms all the more important. The earlier cancer is detected and treated, the greater the chances of recovery are the rule.

The importance of screening for early detection

A variety of screening tests such as mammography for women over 40, colonoscopy from the age of 45 Age or the annual examination of the female sex organs are covered by insurance, since some types of cancer occur more frequently until a certain age. As part of screening often been harmless (benign) nodules are detected, which have so far caused no apparent discomfort. With timely treatment of benign ulcers, cancer may not arise.

In addition, some Cancers otherwise go undetected for years, since it was early cause no symptoms. Bowel cancer can remain asymptomatic for five to ten years, even if the tumor is already malignant.

Even people whose families frequently occurred in a particular type of cancer should be examined regularly, because the probability of falling ill themselves in the same type of cancer is higher due to the genetic predisposition. Certain risk factors should be eliminated wherever possible, although this is obviously not possible in all cases.
