Colon cancer is among the main reasons for death (ranking second after lung cancer for men and after breast cancer for women), and this extremity has been growing fleetly during the last 25 years.   It often spreads to the liver before reaching the lungs, most frequently from colorectal cancer. Rectal cancer produces lung metastases more frequently than colon cancer does. About half of the cases in China are rectal ones, which is more than 30% in the western world.   For lung metastatic or stage IV CRC the cure is determined by the cancer’s extent and the patient’s overall health condition.   Colon and rectal cancers take place in the lower ends of the digestive system that include the large intestine and rectum. However, even in the case of early detection and treatment, including complete removal during initial care, some cases of colorectal cancer can reappear.   When colorectal cancer reappears after initial curative therapy, it constitutes a recurrence or relapse. This recurrence can be local (in the original area or nearby tissues) or at a distant site, known as a metastasis.   Sometimes, colorectal cancer has already spread to distant sites at diagnosis, classifying it as metastatic (stage IV) colorectal cancer.   Factors influencing the cure include:  
  • The cancer's size and location
  • The patient's age and overall health
  • The patient's response to treatment
  Common Metastasis Sites:   Metastatic colorectal cancer frequently spreads to the liver, likely due to the liver's primary blood supply from the portal vein, which carries blood from the intestines and spleen. Other common metastasis sites include:
  • Lungs
  • Brain
  • Abdominal cavity lining
  • Distant lymph nodes
  Symptoms:   Early-stage colorectal cancer might not cause symptoms. However, potential symptoms include:
  • Changes in bowel habits, like diarrhea or constipation
  • Weakness
  • Fatigue
  • Abdominal pain
  • Unintended weight loss
  • Darker or red stools
  • Rectal bleeding with bright red blood
  • Blood in the stool
  As cancer progresses and spreads, symptoms vary depending on the metastasis location. For example:
  • Jaundice and abdominal swelling indicate liver spread
  • Bone pain and fractures suggest bone metastasis
  • Breathing difficulties indicate lung involvement
  • Headaches, dizziness, or seizures suggest brain metastasis
  The American Cancer Society notes a 14% 5-year relative survival rate for metastatic colon cancer. While this statistic may seem alarming, it doesn't consider other factors like varying treatment success rates or individual health impacts on treatment response.   Moreover, these statistics reflect past cases and survival rates will likely improve as medical treatments evolve.
