09 — The In-Between: Nutrition, Port-A-Catheters, Physiotherapy, Massage, Breathing & Fitness

Breast cancer treatment does not consist only of surgery, chemotherapy, radiation, or endocrine therapy. There is an important physiological interval between these major interventions in which the body is healing, adapting, rebuilding tissue, maintaining mobility, and preparing for the next stage of treatment. Nutrition, vascular access, rehabilitation, lymphatic care, breathing mechanics, and physical conditioning are therefore not peripheral concerns; they are part of supportive cancer care.

The exact combination depends on the operation performed, lymph-node treatment, systemic therapy, radiation plan, symptoms, nutritional status, and overall health. The objective is not to force the body to perform normally while it is recovering, but to maintain function while allowing biological repair to occur.

1. Nutrition: Supplying the Materials for Repair

Healing is metabolically demanding. After breast surgery, the body must synthesize collagen, extracellular matrix, cellular membranes, enzymes, immune mediators, and new tissue. Chemotherapy and radiation can further increase fatigue, alter appetite, affect the gastrointestinal tract, and change taste or smell.

The purpose of nutrition during treatment is therefore adequate nourishment rather than dieting.

A balanced dietary pattern should provide:

Protein — required for tissue repair, immune proteins and maintenance of lean muscle.
Carbohydrates — an important source of energy, particularly when appetite is reduced.
Dietary fats — provide energy and essential fatty acids.
Fruits and vegetables — sources of vitamins, minerals, fibre and phytochemicals.
Whole grains and legumes — provide carbohydrates, fibre and additional protein.
Fluids and electrolytes — important for circulation, kidney function and hydration.

During active treatment, maintaining muscle mass and adequate nutritional intake can be more important than intentional weight loss. ASCO recommends dietary, exercise and weight-management interventions according to the individual's cancer treatment and clinical circumstances. (ASCOPubs)

The National Cancer Institute also emphasizes adapting food choices to treatment-related problems such as nausea, appetite loss, mouth sores, swallowing difficulties, diarrhoea, constipation and changes in taste.

Food safety matters

Chemotherapy can reduce immune-cell numbers in some patients. Food should therefore be prepared with careful attention to hand hygiene, refrigeration, cooking temperatures and avoidance of contaminated or spoiled foods.

Supplements require particular caution. More is not necessarily better. High-dose vitamins, minerals, herbal preparations and antioxidant supplements can interact with medications or treatment pathways. Supplements should be discussed with the oncology team or oncology dietitian before use.

2. The Port-A-Catheter: A New Route Into the Circulation

A Port-A-Cath, also called an implanted port or totally implantable venous access device, is a small medical reservoir positioned beneath the skin and connected to a catheter entering a large central vein.

The port generally consists of three functional components:

Port reservoir → self-sealing septum → catheter → central vein

The catheter usually terminates in a large central vein near the heart, allowing chemotherapy, fluids, blood products and other intravenous medications to enter the bloodstream. A port can also be used for blood sampling. (Memorial Sloan Kettering Cancer Center)

Unlike an external central line, the entire port is beneath the skin. When treatment is required, a specially designed non-coring needle passes through the skin into the port's septum.

Why use a port?

Repeated chemotherapy can require frequent venous access. Some medications are also irritating to small peripheral veins. A central port provides reliable access while reducing repeated peripheral needle sticks.

Ports can remain in place for months or years when clinically necessary. (Leeds Teaching Hospitals NHS Trust)

Port complications

Although generally safe, an implanted port can develop:

infection;
thrombosis;
catheter occlusion;
catheter displacement or malfunction;
bleeding or hematoma;
skin irritation;
rarely, complications associated with insertion such as pneumothorax.

Fever, increasing redness, swelling, drainage, significant pain, arm or neck swelling, difficulty flushing the port, chest pain or unexplained shortness of breath should be reported promptly to the medical team.

A port should never be massaged, manipulated or exercised directly without appropriate clinical guidance.

3. Breast Physiotherapy: Restoring Movement After Surgery

Breast and axillary surgery can alter much more than the breast itself.

Removal of breast tissue, sentinel lymph-node biopsy or axillary lymph-node dissection can affect the:

pectoralis major and minor region;
shoulder girdle;
axillary soft tissues;
chest-wall fascia;
skin and scar tissue;
lymphatic drainage;
shoulder range of motion.

Radiation may subsequently make tissues less flexible because of inflammation and later fibrotic changes.

This is why oncologic physiotherapy can be valuable during recovery.

A physiotherapist may assess:

Shoulder → scapula → chest wall → arm → posture → scar → lymphatic function

Early rehabilitation commonly focuses on gentle range-of-motion and functional movement, followed by progressive strengthening as healing permits. Evidence-based guidelines recommend individualized exercise programs after surgery and gradual progression according to the patient's condition. (PubMed Central (PMC))

What physiotherapy can address

Physiotherapy may help with:

reduced shoulder range of motion;
stiffness;
weakness;
postural changes;
scar restriction;
chest-wall tightness;
shoulder and neck discomfort;
reduced functional capacity;
lymphoedema risk or management.

The timing matters. A healing incision, reconstruction, drain, tissue expander, implant or recently irradiated tissue may require specific restrictions.

4. The Lymphatic System and Lymphoedema

The lymphatic system is particularly important after breast cancer surgery because lymph nodes and lymphatic vessels may have been removed, damaged or exposed to radiation.

Most breast lymphatic drainage passes toward regional lymph-node basins, particularly the axillary nodes. The axilla therefore becomes clinically important after sentinel-node biopsy or axillary dissection. (Cancer.gov)

When lymphatic transport is impaired, protein-rich interstitial fluid can accumulate in tissues, producing breast cancer-related lymphoedema (BCRL).

Possible symptoms include:

heaviness;
tightness;
swelling;
altered sensation;
reduced flexibility;
aching or discomfort;
increasing asymmetry of the arm, breast or chest wall.

Importantly, lymphoedema can develop months or years after treatment, not only immediately after surgery. (Cancer.gov)

Early recognition is valuable because intervention can be easier before chronic tissue changes develop.

5. Massage Therapy: What It Can and Cannot Do

Massage has a place in supportive cancer rehabilitation, but it needs to be distinguished from ordinary relaxation massage and from manual lymphatic drainage (MLD).

Manual lymphatic drainage is a specialized, gentle technique intended to influence lymphatic fluid movement. It should be performed by someone appropriately trained in lymphoedema or oncology rehabilitation.

Evidence does not support the idea that vigorous massage can "flush cancer toxins" from the body. Nor should massage be presented as a treatment that kills cancer cells.

Massage may instead have supportive roles involving:

relaxation;
perceived muscle tension;
comfort;
scar and soft-tissue mobility when appropriate;
selected lymphoedema-management programs.

For established breast-cancer-related lymphoedema, complete decongestive therapy may combine compression, exercise, skin care and selected lymphatic techniques. APTA guidelines emphasize individualized treatment rather than assuming that one technique works for every patient. (PubMed Central (PMC))

Areas requiring caution

Massage should not be performed over:

an unhealed incision;
an active infection;
a fresh surgical site;
compromised irradiated skin;
an implanted port;
an area of suspected thrombosis;
a painful or unexplained swelling.

The oncology or rehabilitation team should determine when and how massage is appropriate.

6. Breathing Exercises: The Diaphragm Is Part of Rehabilitation

Breathing is more than oxygen entering the lungs. The respiratory system interacts mechanically with the ribs, thoracic cavity, diaphragm, abdominal cavity and lymphatic circulation.

Diaphragmatic breathing emphasizes movement of the diaphragm during inhalation rather than relying predominantly on accessory muscles of the neck and upper chest.

A simplified breathing cycle is:

Inhalation → diaphragm contracts and descends → thoracic volume increases → air enters lungs

Exhalation → diaphragm relaxes and rises → thoracic volume decreases → air leaves lungs

Following breast or axillary surgery, gentle deep-breathing exercises can help maintain chest-wall mobility and may be incorporated into rehabilitation programs. Some physiotherapy protocols also combine breathing with shoulder movement and lymphatic exercises. (PubMed Central (PMC))

Breathing exercises are supportive rehabilitation, not an anti-cancer therapy.

7. Body Fitness: Conditioning the Body Rather Than Punishing It

Cancer treatment can reduce activity through fatigue, pain, nausea, neuropathy, surgery and treatment schedules. Prolonged inactivity can then produce deconditioning—loss of cardiovascular fitness, muscle strength and functional capacity.

Exercise helps interrupt that cycle.

ASCO recommends aerobic and resistance exercise during active cancer treatment with curative intent when medically appropriate. Evidence indicates that exercise can reduce treatment-related fatigue and help preserve cardiorespiratory fitness, physical function and strength. (ASCOPubs)

The American Cancer Society similarly recommends regular physical activity, progressing gradually, and muscle-strengthening activity at least twice weekly for cancer survivors. (American Cancer Society)

The progression

A rehabilitation program may gradually move through:

Breathing → mobility → walking → aerobic conditioning → resistance training → functional strength

Examples can include:

walking;
stationary cycling;
gentle swimming when wounds and ports permit;
mobility exercises;
resistance bands;
light weights;
body-weight exercises;
posture and scapular strengthening.

For patients at risk of lymphoedema, resistance exercise is not automatically prohibited. Evidence supports appropriately supervised, progressive resistance training rather than permanent avoidance of loading the affected arm. (PubMed Central (PMC))

The principle is progressive loading, not sudden exertion.

The Biology of the In-Between

The interval between surgery and subsequent treatment is sometimes perceived as a period of waiting. Biologically, it is anything but passive.

During this period, the body is simultaneously:

Repairing tissue
↓
Remodelling extracellular matrix and scar
↓
Restoring movement
↓
Re-establishing lymphatic and vascular function
↓
Maintaining muscle and cardiovascular capacity
↓
Preparing for the next treatment

Nutrition supplies substrates. Physiotherapy restores mechanical function. Breathing maintains thoracic mobility. Physical activity preserves muscle and cardiovascular capacity. Appropriate lymphatic management helps address swelling and tissue fluid imbalance. A port provides dependable vascular access when systemic treatment requires it.

Together, these interventions form a bridge between treatment and recovery.

Breast cancer care therefore extends beyond removing a tumour or administering a drug. It also involves preserving the body's ability to move, heal, nourish itself, circulate fluid, breathe efficiently and rebuild functional capacity.
