What Is Colon Cancer?

Colon cancer is a type of colorectal cancer that develops in the colon, the main portion of the large intestine responsible for absorbing water and forming stool. It most often begins as a precancerous polyp and progresses slowly over time, making early detection and expert surgical care critical for long-term outcomes.

Colon cancer can cause symptoms such as changes in bowel habits, abdominal discomfort, rectal bleeding, unexplained anemia, fatigue, or weight loss. Because these symptoms can overlap with less serious conditions, evaluation by a highly trained colorectal specialist is essential. If you are seeking the best colon cancer surgery in Los Angeles, Dr. Karen Zaghiyan is widely trusted for her precise, minimally invasive, and organ-preserving surgical approach.

Signs and Symptoms of Colon Cancer

Colon cancer may present subtly in its early stages and become more noticeable as the disease progresses. Prompt evaluation ensures accurate diagnosis and timely treatment.

Common symptoms include:

Changes in bowel habits (diarrhea, constipation, or narrowing of stools)
Abdominal pain, bloating, or cramping
Rectal bleeding or blood in the stool
Unexplained anemia or chronic fatigue
Unintentional weight loss

How Is Colon Cancer Treated?

Dr. Zaghiyan, recognized as one of the best colon cancer surgeons in Los Angeles, provides highly specialized care centered on minimally invasive, organ-sparing surgery whenever possible. Treatment begins with comprehensive imaging and diagnostic evaluation to determine tumor location, stage, and whether the cancer has spread.

Surgery is the cornerstone of colon cancer treatment and is carefully tailored to remove the cancer completely while preserving normal bowel function. Dr. Zaghiyan offers advanced robotic and laparoscopic colectomy techniques that reduce trauma, shorten recovery time, and improve functional outcomes.

Colon Cancer Surgery Options

Preoperative Evaluation

Patients with colon cancer undergo thorough imaging, including CT scans, to assess the extent of disease and rule out spread to other organs. This allows for precise surgical planning and optimal outcomes.

Minimally Invasive Colectomy

Most patients are candidates for robotic or laparoscopic colectomy, during which the affected portion of the colon is removed through small incisions. These advanced techniques allow for:

Greater surgical precision
Less postoperative pain
Shorter hospital stays
Faster return to daily activities

As the best colon cancer surgeon in Los Angeles, Dr. Zaghiyan’s focus on organ preservation ensures that only the diseased portion of the colon is removed while maintaining bowel continuity and normal digestive function whenever possible.

Multidisciplinary Care When Needed

For patients with more advanced colon cancer, treatment may involve a combination of surgery, chemotherapy, or immunotherapy. As a leader in multidisciplinary cancer care, Dr. Zaghiyan collaborates closely with oncologists, radiologists, and pathologists to determine the most effective treatment sequence for each individual patient.

What to Expect During Colon Cancer Surgery

Before surgery, Dr. Zaghiyan carefully reviews each patient’s diagnosis, imaging, and treatment options, ensuring clarity and confidence at every step.

Before Surgery

Personalized consultation, imaging review, and preoperative preparation to optimize safety and outcomes.

During Surgery

Advanced robotic or laparoscopic techniques are used to precisely remove the cancer while preserving bowel function. Multimodal pain control and nerve-sparing strategies help minimize discomfort.

After Surgery

Close postoperative monitoring, detailed recovery guidance, and ongoing support to restore bowel function and quality of life.

Minimally invasive surgery allows many patients to recover more quickly and return home sooner compared to traditional open surgery.
