Overview

This section provides a short and straight to the point overview of the disease or symptom. The first sentence of the overview must contain the name of the disease.

Common Cancers

Breast Cancer

• Breast cancer screening starts at the age of 50 via a mammogram twice a year and discontinues at the age of 74.
• According to the GLOBOCAN 2018 estimates of cancer incidence, mortality, and prevalence, breast cancer is the most commonly diagnosed cancer and the leading cause of cancer deaths among females (11.6% of total cancer deaths).

Recommendations for Breast cancer screening:
Population	Screening recommendations
Age 50	Mammogram (every 2 years)
Age 40	Mammogram recommended only for population with risk factors of breast cancer such as: Early menarche Nulliparity First degree relative who has had breast cancer
Age 21-29	Pap test (cytology) every 3 years
Age 30-65	Cytology every 3 years or Cytology and HPV testing (co-testing) every 5 years
Age 65 or greater than 65	Discontinue cervical cancer screening Age 65 with no risk for cervical cancer (e.g., immunosuppression, high risk sexual activity, tobacco use, diethylstilbestrol exposure) or hysterectomy and No history of cervical intraepithelial neoplasia grade 2 or higher and 3 consecutive negative pap tests or 2 consecutive negative co-testing results

Cervical Cancer

• Cervical cancer screening starts at the age of 21 regardless of the onset of sexual activity via Papanicolaou test (Cervical cytology).
• According to the GLOBOCAN 2018 estimates of cancer incidence, mortality, and prevalence, cervical cancer ranks fourth for both incidence and mortality among females.

Recommendations for Cervical cancer screening:
Population	Screening recommendations
Immunocompromised	onset of sexual intercourse
Age less than 21	screening not recommended
Age 21-29	Pap test (cytology) every 3 years
Age 30-65	Cytology every 3 years or Cytology and HPV testing (co-testing) every 5 years
Age 65 or greater than 65	Discontinue cervical cancer screening Age 65 with no risk for cervical cancer (e.g., immunosuppression, high risk sexual activity, tobacco use, diethylstilbestrol exposure) or hysterectomy and No history of cervical intraepithelial neoplasia grade 2 or higher and 3 consecutive negative pap tests or 2 consecutive negative co-testing results

Colorectal Cancer

• Colorectal cancer screening starts among asymptomatic adults at the age of 50 with no family history of adenoma or colorectal cancer (CRC). It is preferably done via colonoscopy
• According to the GLOBOCAN 2018 estimates of cancer incidence, mortality, and prevalence, Colon cancer is the fourth commonly occurring cancer (6.1% for incidence). It is the third cause of death in cancer patients (9.2% of total cancer deaths).

Recommendations for Colorectal cancer screening:
Population	Screening recommendations
Age 50 asymptomatic with no history of CRC or adenoma	Direct Visualization Tests Colonoscopy (every 10 years) Flexible sigmoidoscopy (every 5 years) Flexible sigmoidoscopy (every 10 years) with fecal immunochemical test (every year) CT colonography (every 5 years) Stool-Based Tests Guaiac-based fecal occult blood test (gFOBT) (every year) Fecal immunochemical test (FIT) (every year) Multitargeted stool DNA test (FIT-DNA) (every 1 year or 3 years)
Family history of CRC or adenomatous polyps 1 First-degree relative age <60 Multiple first-degree relatives at any age	Colonoscopy at age 40 or 10 years before the age of diagnosis in affected relative (every 5 years)
Inflammatory bowel disease Ulcerative colitis Crohn disease with colonic involvement	Colonoscopy 8-10 years after diagnosis (every 1-3 years)
Hereditary nonpolyposis colorectal cancer	Colonoscopy at age 20-25 (every 1-2 years)
Familial adenomatous polyposis	Colonoscopy at age 10-12 (every year)

Lung Cancer

• Lung cancer screening starts among asymptomatic adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit smoking within the past 15 years.
• According to the GLOBOCAN 2018 estimates of cancer incidence, mortality, and prevalence, Lung cancer is the most commonly diagnosed cancer (11.6% of the total cases) and the leading cause of cancer death in both males and females (18.4% of the total cancer deaths).

Recommendations for lung cancer screening:
Recommended test	Low-dose chest CT
Recommended Interval	Annual screening (every year)
Age for screening	55-80
Eligibility for screening based on smoking history	Patient has 30 or greater than 30-pack-year smoking history and patient is a current smoker or quite smoking within the last 15 years.
Discontinuation of screening	Age greater than 80 or Patient successfully quit smoking for 15 years and beyond or Patient has other medical problems that significantly limit life expectancy or ability/willingness to undergo lung cancer surgery.

Ovarian cancer

• There are no recommendations for screening ovarian cancer in asymptomatic women although the better outcome is associated with early diagnosis.

Prostate Cancer

• According to the GLOBOCAN 2018 estimates of cancer incidence, mortality, and prevalence, Prostate cancer is the second cause of cancer deaths in males (7.1% of the total cancer deaths).
