Cancer is one of the major health challenges worldwide, affecting millions of lives each year. However, early detection through cancer screening can play a vital role in reducing mortality and increasing the chances of successful treatment.
What is Cancer Screening?
Screening is a process in which individuals at risk, based on factors such as age, family history, genetic factors, and high prevalence of a certain type of cancer in the family, are evaluated. The goal of these tests is to identify the disease in its early stages, before symptoms appear, to prevent its progression and improve treatment success rates.
By conducting screening tests, abnormal cells can be detected before clinical signs of cancer appear, allowing for treatment to be initiated as quickly as possible. This method not only prevents complications and higher medical costs but also enables patients to manage the disease with less invasive methods. Therefore, screening is one of the most effective strategies for prevention and reducing cancer-related mortality.
Benefits of Cancer Screening
Screening helps with early detection and increases the chances of successful cancer treatment. These tests can identify abnormal changes and take necessary actions swiftly. One of its most important benefits is identifying precancerous cells that may turn into cancer. Early detection leads to faster, more cost-effective, and more efficient treatment, resulting in a higher chance of recovery and longer life expectancy. Therefore, regular screening is one of the essential actions for maintaining health and reducing cancer-related deaths.
Goals and Criteria of Cancer Screening
- Detection Before Symptoms Appear: These tests can identify abnormal changes in the body, even when symptoms have not yet manifested.
- Increase the Likelihood of Successful Treatment: Early detection leads to less invasive and more effective treatment methods.
- High Accuracy of Results: Screening tests should have the lowest possible false positives or false negatives to ensure more accurate diagnosis.
- Reduction in Cancer Mortality: Early detection can play a significant role in reducing mortality rates and improving the quality of life for patients.
Who Should Undergo Screening?
- Personal history of cancer
- Family history of cancer
- Genetic mutations
- Exposure to carcinogens
- Unexplained blood clots
- Increasing age
Cancers Commonly Screened For:
- Breast Cancer: Mammography
- Colorectal Cancer: Colonoscopy, Fecal occult blood test
- Cervical Cancer: Pap smear, HPV test
Can Cancer Screening Help Increase Patient Lifespan?
Screening, through early disease detection, increases the chances of successful treatment and reduces cancer mortality rates. Tests like mammograms, sigmoidoscopies, and fecal occult blood tests for breast and colorectal cancer can help identify the disease early and reduce mortality from these cancers.
Screening is an important strategy in reducing mortality rates and improving the quality of life for at-risk individuals. Therefore, undergoing regular screenings as per medical recommendations can help maintain health and increase the lifespan of patients.
Appropriate Age for Cancer Screening and Its Costs
Cancer screening is one of the most important actions for early detection and increasing the likelihood of successful treatment. This process is recommended at different ages depending on the type of cancer, its prevalence, and the risk groups.
What Age is Suitable for Screening?
- Breast Cancer: In our country, breast cancer screening is the most common. It is recommended that women begin mammography every two years starting at age 50, and this should continue until the age of 70.
- Cervical Cancer: This is one of the most common cancers among women. For early detection, a Pap smear test is recommended three years after marriage or the first sexual contact, and it should be repeated regularly as per the doctor’s advice.
- Colorectal Cancer: This cancer is also particularly common in older ages. It is recommended that individuals over the age of 60 undergo sigmoidoscopy, and if the result is negative, the test should be repeated every five years. Additionally, a fecal occult blood test is considered as a supplementary method, though its accuracy and standards are lower than other methods.
Importance of Early Cancer Detection
Early cancer detection has a significant impact on increasing the chances of successful treatment. This includes two key aspects:
- Attention to Early Symptoms: Awareness of warning signs and timely visits to a doctor can be highly effective in early diagnosis.
- Regular Screening: Undergoing screening tests as per the doctor’s recommendations, even in the absence of symptoms, can help detect cancer at its early stages.
Cancer Screening Costs
Currently, there is a lot of research being conducted to find cost-effective and efficient screening methods. For example, visual inspection with acetic acid may be used in the future as an affordable method for cervical cancer screening. Studies are also underway to replace more expensive methods like mammography with cheaper alternatives.
At Shafa Clinic, screening tests are performed at an affordable cost under the supervision of specialized doctors. Individuals can visit this center to benefit from services related to screening and early cancer detection.
Cancer Screening Results and Challenges
Screening plays a vital role in early cancer detection, but like any medical procedure, it may come with some challenges.
Potential Challenges of Cancer Screening
- Medical Side Effects: Some screening tests can lead to minor health issues like bleeding, especially with more invasive methods like biopsy or colonoscopy.
- False Positive Results: A common issue in screening is receiving a false positive result, meaning the test indicates the person has cancer, even when no cancer is present.
- Overdiagnosis: Sometimes screening may identify a cancer that grows very slowly and will not cause any problems during the person’s lifetime.
The Importance of Consulting a Doctor Before Screening
Given these challenges, it is recommended to consult a specialist doctor before undergoing screening to choose the best method suited to your individual condition. The doctor can determine which test is most appropriate based on your risk factors, family history, and overall health, and avoid unnecessary tests.
Types of Cancer Screening
Cancer screening refers to methods that allow the detection of cancer before symptoms appear, enabling early treatment.
Colorectal Cancer Screening
Colorectal cancer includes cancers of the large intestine and rectum. One of the most important screening methods for this type of cancer is colonoscopy. In this procedure, a microscopic device called a colonoscope is inserted through the anus into the large intestine to closely examine lesions and polyps.
Mesothelioma Cancer Screening
Mesothelioma is a rare cancer that starts from the lining tissues of organs. It has various types, categorized based on the location of the tumor. These types include pleural mesothelioma (lung), peritoneal mesothelioma (abdomen), pericardial mesothelioma (heart), and testicular mesothelioma (testicles).
Lung Cancer Screening
Lung cancer is one of the most common types of cancer, especially prevalent among smokers and those exposed to asbestos or radon. One of the primary screening methods for lung cancer is low-dose spiral computed tomography (LDCT), which is usually recommended for individuals who are smokers or have a long history of smoking.
Colorectal Cancer Screening
Colorectal cancer, which includes cancer of the large intestine and rectum, is the third most common cancer globally. Screening for this cancer is crucial as it can identify the disease in its early stages and prevent deaths from it. The most common screening method is colonoscopy, where a thin tube called a colonoscope is inserted through the anus into the large intestine to detect abnormalities and potential lesions such as polyps or tumors.
Breast Cancer Screening
Breast cancer screening is another critical step in the early detection of cancer. Mammography is commonly used to create images of the breast tissue. This imaging can identify cancer up to 10 years before visible symptoms appear. In advanced countries like the UK, mammography is performed as a national screening test for all women and has helped reduce breast cancer mortality.
Cervical Cancer Screening
Cervical cancer is one of the leading causes of death among women, but with appropriate screenings, it can be detected before it spreads to other parts of the body. Cervical cancer screening is typically done through a Pap smear test and the human papillomavirus (HPV) test. These tests help identify cellular abnormalities and specific viruses that can lead to cancer.
Liver Cancer Screening
Another important screening test for cancer detection is the alpha-fetoprotein (AFP) blood test. This test measures the level of AFP in the blood, which can indicate liver diseases, including liver cancer.
Ovarian Cancer Screening
For ovarian cancer screening, the CA-125 blood test and transvaginal ultrasound are commonly performed. These tests help detect ovarian cancer in women at high risk.
Prostate Cancer Screening
For men, the PSA test is used to detect prostate cancer. This test measures the level of a specific antigen in the blood, which, if elevated, may indicate prostate cancer.
Stomach Cancer Screening
For stomach cancer, endoscopy is used. This method involves inserting a tube with a camera into the stomach, allowing the doctor to identify potential tumors.
Benefits of Cancer Screening
- Preparation for Chemotherapy in Breast Cancer
Chemotherapy in Gorgan is one of the most common methods for treating breast cancer. In many cases, especially in advanced stages of the disease, it may be considered a primary treatment option.
- High Success Rate in Cancer Treatment
Breast cancer treatment can be highly successful if detected in its early stages. One of the key factors in increasing treatment success is early and timely diagnosis, which leads to the initiation of effective treatments and reduces the likelihood of cancer progression.
- Lower Costs with Early Detection
Screening and preventive tests can significantly reduce treatment costs. Early diagnosis allows individuals to receive more affordable and effective treatments.
- Prevention of Cancer
Cancer prevention, especially through screening, plays a vital role in reducing the risk of developing the disease. Screening tests can identify the risk of cancer and provide necessary warnings to prevent its progression.
Types of Cancer Screening Methods
Screening involves methods that help identify cancer or its signs at an early stage. Some common screening methods include:
- Chest X-ray: Used to detect lung cancer and cancers that have spread from other parts of the body to the lungs.
- Blood Tests: Used to detect tumors and diagnose certain types of cancer such as colorectal, liver, breast, testicular, prostate, thyroid, and lung cancers.
- Mammography: Recommended for women over 40 to detect breast cancer.
- Ultrasound: Used to detect malignant tumors in the abdomen, pelvis, liver, and ovaries.
- Urine Tests: Used to check for malignant cells in the kidneys, ureters, bladder, and prostate.
- Fecal Occult Blood Test: Used to detect colorectal cancer, particularly in individuals with a family history or symptoms like sudden weight loss or urinary incontinence.
- CT Scan: Used to identify hidden tumors in areas like the head, neck, prostate, colon, and lungs.
Important Tests in Cancer Screening
Screening is a tool for detecting cancers at an early stage when treatments are more effective.
- Virtual Colonoscopy
This imaging method allows the observation of the colon and rectum from outside the body. Although it does not definitively show that mortality from colorectal cancer is reduced, it is a good option for individuals who have no symptoms or do not want to undergo conventional colonoscopy.
- Transvaginal Ultrasound
This imaging test uses sound waves to create images of the ovaries and uterus. It is especially recommended for women at high risk of ovarian or endometrial cancer (due to BRCA1 or BRCA2 gene mutations or family history).
- Skin Examination
Individuals at risk for skin cancer should regularly examine their skin or consult a dermatologist. Changes in moles or skin (such as new moles or changes in existing moles) should be reported to a doctor immediately.
- PSA Test
This blood test is used for prostate cancer screening in men. However, some expert groups recommend that this test not be performed routinely for all men, as many prostate cancers detected by PSA testing are non-lethal, and early treatments may not significantly impact mortality reduction.
- Multicancer Early Detection Tests
These tests look for biological signals in bodily fluids that may be secreted by cancer cells. These signals are known as biomarkers or tumor markers. These tests may detect multiple types of cancer, but their effectiveness for screening cancer in asymptomatic individuals is not yet proven and requires further evaluation.
- CA-125 Test
The CA-125 blood test is typically used to screen for ovarian cancer in women at high risk, especially those with a family history. This test can help in detecting ovarian cancer and assessing recurrence in women with a history of ovarian cancer. However, it is not yet confirmed as an effective screening test.
