Colorectal tumors account for 10% of all malignant cancers in women and 12% in men. Incidence  is higher in the male population, especially among younger individuals. It is commonly believed that colorectal cancer is  predominantly associated with advanced age. However, colorectal surgeons, who specialize in the treatment of this type of  cancer, are observing a growing number of cases among middle-aged and younger individuals.&lt;\/br&gt;  &lt;b&gt;&lt;br&gt;Aim:&lt;\/b&gt; The aim of our study was to investigate whether colorectal cancer still predominantly affects elderly individuals, how  frequently it is diagnosed in younger patients, and whether the location of tumors in the intestines of younger patients aligns  with data from elderly individuals.&lt;\/br&gt;  &lt;b&gt;&lt;br&gt;Materials and methods:&lt;\/b&gt; The study was conducted retrospectively and included a cohort of 1771 patients who underwent surgical  procedures due to colorectal cancer between 2012 and 2015 at the Department of General and Colorectal Surgery at the Medical  University of \u0141\u00f3d\u017a and between 2014 and 2017 at the Department of General Surgery with a Division of Surgical Oncology at the  District Health Center in Brzeziny. Data were analyzed regarding the frequency of colorectal cancer occurrence by age, tumor location  in different age groups, and disease stage according to age. Age groups included &lt;40 years, 41\u201350 years, 51\u201370 years, and &gt;70 years.&lt;\/br&gt;  &lt;b&gt;&lt;br&gt;Results:&lt;\/b&gt; The study encompassed a total of 1771 patients, with 988 (55.79%) being males and 783 (44.21%) females. The mean  age of the patients was 65.27 11.12 years. The highest number of cases was observed in the age range of 60\u201370 years and 70-80 years. It was found that colorectal tumors in males more frequently occurred on the left side of the colon and rectum,  while in females, they were more commonly located on the right side of the colon, which was statistically significant (P = 0.007). Younger age groups of patients (&lt;40 years, 40\u201350 years) had a similar male-to-female ratio, whereas in age groups above 50 years, males significantly outnumbered females (P = 0.049). The study revealed that in the group of patients below 40 years of age, an advanced stage of colorectal cancer was significantly more common; stage D occurred over twice as often  as in the 51\u201370 age group and over three times as often as in the &gt;70 age group.&lt;\/br&gt;  &lt;b&gt;&lt;br&gt;Conclusions:&lt;\/b&gt; The incidence of colorectal cancer in Poland is steadily increasing, with a growing number of diagnoses in  younger individuals. Research findings demonstrate that males, especially those in younger age groups, are at a higher risk of  developing colorectal cancer. A higher disease stage is more frequently observed in younger patients, possibly due to delayed  diagnosis and symptomatic treatment. Screening programs should be adjusted to the changing age groups at higher risk. Our  study underlines the need to raise public awareness regarding colorectal cancer, particularly among the younger population.&lt;\/br&gt;<\/jats:p>","DOI":"10.5604\/01.3001.0054.0956","type":"journal-article","created":{"date-parts":[[2024,1,26]],"date-time":"2024-01-26T14:04:51Z","timestamp":1706277891000},"page":"41-45","source":"Crossref","is-referenced-by-count":9,"title":["Colorectal Cancer: Is it Still a Disease of the Elderly?"],"prefix":"10.5604","volume":"96","author":[{"given":"Renata","family":"K\u0119dzia-Berut","sequence":"first","affiliation":[{"name":"Department of General and Colorectal Surgery, Military Medical Academy Memorial Teaching Hospital, Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maciej","family":"Berut","sequence":"additional","affiliation":[{"name":"Department of General Surgery with Subdivision of Oncological Surgery, District Health Center in Brzeziny, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"W\u0142odarczyk","sequence":"additional","affiliation":[{"name":"Department of General and Cancer Surgery, Central Clinical Hospital of the Medical University of Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakub","family":"W\u0142odarczyk","sequence":"additional","affiliation":[{"name":"Department of General and Cancer Surgery, Central Clinical Hospital of the Medical University of Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0390-0827","authenticated-orcid":false,"given":"\u0141ukasz","family":"Dziki","sequence":"additional","affiliation":[{"name":"Department of General and Cancer Surgery, Central Clinical Hospital of the Medical University of Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5439-6237","authenticated-orcid":false,"given":"Adam","family":"Dziki","sequence":"additional","affiliation":[{"name":"Department of General and Colorectal Surgery, Military Medical Academy Memorial Teaching Hospital, Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6290-1806","authenticated-orcid":false,"given":"Micha\u0142","family":"Mik","sequence":"additional","affiliation":[{"name":"Department of General and Colorectal Surgery, Military Medical Academy Memorial Teaching Hospital, Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3689","reference":[{"key":"615367r1","doi-asserted-by":"crossref","unstructured":"Whita A., Ironmorgen L., Steele R. et al.: Areview of sex-related differencesin colorectal cnacer incidence, screening uptake, routes to diagnosis, cancerstage and survival in the UK.
