🔍 Quick Breakdown
Some cancer cells fit leave where the cancer first start, enter nearby tissue, blood or lymph system and later grow for another part of the body.
Doctors dey call this process metastasis.
No be every cancer go spread, and different cancers get different ways and speed wey dem fit take spread.
👉🏾 Even when cancer spread reach another organ, e still remain the same type of cancer from where e originally start.
🟧 Wetin doctors mean when dem say cancer don spread?
Cancer spread no mean say cancer just suddenly “jump” from one organ enter another.
Before cancer fit spread, some cancer cells need to:
• leave the original tumour
• enter nearby tissue, blood or lymph vessels
• survive as dem dey travel
• reach another part of the body
• begin grow for the new place
👉🏾 Na this whole process doctors dey call metastasis.
🟧 Which road cancer cells dey use?
Cancer cells mainly get three ways wey dem fit take move.
• Nearby tissue
→ cancer fit gradually grow enter tissue wey dey around where e start.
• Lymph system
→ cancer cells fit enter lymph vessels and sometimes reach nearby lymph nodes.
• Bloodstream
→ some cancer cells fit enter blood vessels and travel reach distant organs.
👉🏾 Different cancers get places wey dem dey more likely spread reach.
🟧 Why some cancer fit spread?
Normal body cells usually stay where dem belong.
But some cancer cells develop changes wey allow them to:
• separate from other cells
• enter surrounding tissue
• enter blood or lymph vessels
• survive outside where dem originally grow
• start growing for another organ
👉🏾 The ability to invade and spread na one major difference between malignant and benign tumour.
🟧 How you go know if cancer don spread?
Sometimes person no go notice any new symptom.
If symptoms develop, e depend on where the cancer spread reach.
For example:
• bone → persistent bone pain
• lungs → cough or difficulty breathing
• liver → swollen stomach or yellow eyes
• brain → headache, weakness or seizure
👉🏾 These symptoms no automatically mean cancer don spread. Plenty other medical conditions fit cause them too.
🟧 One important thing people dey misunderstand
Imagine say person get breast cancer and later doctors discover cancer cells for the bone.
That one no mean say the person don develop bone cancer.
Because the cells originally come from breast cancer, doctors still call am metastatic breast cancer.
The same principle apply to other cancers.
👉🏾 Cancer dey carry the identity of where e originally start—not where e later spread reach.
🟧 Wetin you fit do
If person already dey receive cancer treatment:
• attend follow-up appointments
• complete recommended scans and tests
• tell your healthcare team about new symptoms
• take medicines as prescribed
• ask questions if you no understand your cancer stage or treatment
👉🏾 New symptom no automatically mean cancer don spread, but your healthcare team need know so dem fit properly assess am.
🟧 Real life example
Mrs Amina dey receive treatment for breast cancer.
Months later, she begin notice persistent pain for her hip.
At first:
• she think say maybe na arthritis
• she fear to tell doctor because she no want hear bad news
During her next appointment, she finally mention the pain. Doctor arrange further tests, and the scan show say the breast cancer don spread reach one part of her bone.
Her cancer team explain the result and discuss treatment options with her.
After she understand, she decide to:
• continue her cancer treatment
• take treatment to help control the bone problem
• report new symptoms earlier instead of keeping quiet because of fear
👉🏾 Knowing where the cancer spread reach help her doctors choose treatment wey fit her situation.
👉🏾 Cancer spreading na serious development—but e no automatically mean say treatment don finish.
🟧 🩺 When you suppose go hospital 🚨
• sudden weakness or person no fit move part of the body
• seizure or sudden confusion
• severe difficulty breathing
• severe back pain with weakness or numbness
• person lose control of urine or stool together with severe back pain
👉🏾 These symptoms fit mean serious complication. Seek urgent medical care.
🟢 Final Reassurance
Metastatic cancer serious, but doctors still get different treatments wey fit slow the cancer, shrink am, control symptoms and sometimes keep the disease under control for a long time.
Treatment depend on the type of cancer, where e spread reach and the person's overall health.
👉🏾 If cancer don spread, no assume say nothing fit be done. Your cancer team still get important treatment decisions to discuss with you.
