16 organ systems covering 466 cancers, drawn as rotating wireframes in the site's style. Each shows where the cancer's subtypes begin (the marked subsites) and the lymph node stations it drains to, which is what staging scans, sentinel node biopsies and radiotherapy fields are built around.
Most cancers start in the ducts and drain first to the axillary nodes, which is why the armpit is checked and a sentinel node is sampled.

Hepatocellular carcinoma grows in a cirrhotic liver and spreads first inside it and into the portal vein, so staging depends on liver function and vascular invasion as much as on size.
Same organ: Early hepatocellular carcinoma (BCLC 0 and A), Intermediate hepatocellular carcinoma (BCLC B), Advanced hepatocellular carcinoma (BCLC C), Hepatoblastoma
About three quarters of cancers arise in the peripheral zone at the back of the gland, the part a finger or a biopsy needle reaches; drainage is to the obturator and iliac nodes.

Each skin cancer comes from a different cell layer: melanocytes and basal cells at the base of the epidermis, keratinocytes above them, Merkel cells and blood vessels in the dermis; depth of invasion decides the risk.
Same organ: Basal cell carcinoma, Cutaneous squamous cell carcinoma, Merkel cell carcinoma, Kaposi sarcoma, Skin cancer (all types), BRAF V600-mutant melanoma, Stage III melanoma (after surgery), Stage IIB and IIC melanoma, Advanced melanoma (unresectable stage III and stage IV), Mucosal melanoma, Acral melanoma, Advanced cutaneous squamous cell carcinoma, Locally advanced and metastatic basal cell carcinoma, Bowen's disease (squamous cell carcinoma in situ), Dermatofibrosarcoma protuberans
Uveal melanoma arises in the pigmented choroid and ciliary body, retinoblastoma in the retina of infants; the eye has no lymphatics, so spread is through the blood (uveal melanoma almost always to the liver).
No lymphatic drainage: spread is haematogenous (uveal melanoma to the liver) or along the optic nerve (retinoblastoma).
Same organ: Optic pathway glioma, Uveal melanoma, Retinoblastoma
Gliomas infiltrate along white matter and can cross the corpus callosum, medulloblastoma sits in the cerebellum, and CNS lymphoma favours deep periventricular tissue; none spread through lymph nodes.
No conventional lymphatics: gliomas spread along white matter tracts and, rarely, through cerebrospinal fluid; medulloblastoma can seed the spine.

Leukaemias, myeloma and MDS live in the marrow and blood; lymphomas grow in lymph nodes and spleen. The node stations are the disease map, not a route of spread, and staging counts them.
In lymphoma the node stations are the disease itself; staging (Ann Arbor / Lugano) counts how many regions and sides of the diaphragm are involved.

Bone sarcomas favour the fast-growing ends of long bones (osteosarcoma) or the shaft (Ewing), soft tissue sarcomas the deep muscle compartments; spread is through the blood to the lungs, rarely via lymph nodes.
Lymph node spread is rare (except epithelioid, synovial, clear cell and rhabdomyosarcoma); sarcomas go through the blood to the lungs.
