Cancer Nutrition

Evidence-based nutrition care for every phase of cancer.

Newly diagnosed and trying to make sense of it. In active treatment and managing side effects. Or finished treatment and wondering what to eat now. Care is individualized to your diagnosis, treatment plan, symptoms, labs, and food preferences — with deep experience across solid and hematologic cancers.

Three phases of care

Where are you in your cancer journey?

The goals of nutrition care shift over time. Each phase has its own priorities.

Newly diagnosed

The window between diagnosis and the start of treatment is the most valuable time to optimize nutrition. Care during this phase typically focuses on:

  • Baseline nutrition assessment and goal-setting
  • Building reserve: protein, calories, micronutrients
  • Identifying treatment-specific risks (e.g., head & neck, GI)
  • Reviewing supplements for treatment interactions
  • Practical food prep and grocery planning for treatment days

In active treatment

Chemotherapy, radiation, surgery, hormonal therapy, targeted therapy, immunotherapy, or stem cell transplant. The work is symptom-specific and updated cycle by cycle:

  • Nausea, vomiting, taste change, dry mouth, mucositis
  • Diarrhea, constipation, early satiety, swallowing difficulty
  • Unintentional weight loss, muscle loss, cachexia
  • Neutropenia and food safety
  • Lab review and coordination with the oncology team

Survivorship

After active treatment ends, nutrition priorities change. The focus shifts to long-term health, rebuilding, and reducing recurrence risk where evidence supports it:

  • Rebuilding muscle and energy after treatment
  • Long-term eating patterns supported by oncology nutrition evidence
  • Weight management without restrictive cycling
  • Managing late effects (GI, bone health, cardiac, metabolic)
  • Food-and-cancer questions: soy, sugar, dairy, alcohol, supplements
Who this is for

Cancers commonly seen in this practice

Care is provided for adults with any cancer diagnosis. Particular clinical depth in the following:

GI cancers

Esophageal, gastric, pancreatic, hepatobiliary, colorectal, anal, and post-surgical recovery (gastrectomy, Whipple, esophagectomy, colectomy). These often need significant adjustment in eating mechanics, macronutrient distribution, and supplementation.

Head & neck cancers

Radiation and surgery to the head and neck typically affect chewing, swallowing, saliva, and appetite. Nutrition support — including tube feeding when needed — is often essential to maintaining treatment.

Hematologic cancers

Leukemia, lymphoma, myeloma. Care includes neutropenic considerations, stem cell transplant nutrition, steroid-related weight and glucose changes, and long-term survivorship needs.

Breast, gynecologic, prostate, and other solid tumors

Treatment-related weight change, hormonal therapy effects, GI side effects from pelvic radiation, and survivorship eating patterns aligned with the most current oncology nutrition evidence.

What to expect

How care works

  1. 1. Free 15-minute consult

    A brief call to confirm fit, discuss your diagnosis and goals, verify insurance, and recommend the right package or session type. No obligation.

  2. 2. Initial assessment (60 minutes)

    A thorough intake: diagnosis, treatment plan, surgical history, medications and supplements, labs, weight history, symptoms, food preferences, culture, and goals. You leave with an initial plan and next steps.

  3. 3. Follow-ups (30 minutes)

    Plans are adjusted as your treatment, side effects, labs, and goals evolve. Messaging between sessions is available for time-sensitive questions in package plans.

  4. 4. Coordination with your team

    With your written consent, communication with your oncologist, surgeon, infusion nurse, or home health team is part of the standard of care.

FAQ

Cancer nutrition questions

When should I start working with an oncology dietitian after a cancer diagnosis?

As soon as possible. Early nutrition optimization before and during treatment is associated with better treatment tolerance, fewer treatment interruptions, faster recovery, and improved muscle preservation. Starting early also makes weight, lab, and symptom changes easier to address before they become harder problems.

What cancer treatment side effects can nutrition help with?

Common side effects that respond to nutrition strategies include nausea, vomiting, taste and smell changes, dry mouth, mucositis and mouth sores, swallowing difficulty, early satiety, diarrhea, constipation, fatigue, neuropathy-related eating issues, unintentional weight loss, and muscle loss (sarcopenia). Plans are individualized to your treatment, diagnosis, and symptom pattern.

Is there a single “cancer diet”?

No. There is no single cancer diet that fits every diagnosis and every phase. Nutrition needs differ depending on cancer type, stage, treatment plan, side effects, comorbidities, weight history, and personal and cultural food preferences. The plan you receive is built around your situation, not a template.

What about supplements during cancer treatment?

Some supplements can interact with chemotherapy, radiation, immunotherapy, and surgical recovery. Supplement review is part of the standard intake. Recommendations are individualized and coordinated with your oncology team when appropriate.
